Description

Technical Field

[0001] This invention belongs to the field of elevator inspection technology, specifically relating to a tool for detecting elevator sill gaps and leveling accuracy. Background Technology

[0002] Elevators are a type of vertical transportation that people use very frequently in their daily lives. To ensure the safety of passengers entering and exiting the elevator car, relevant elevator standards have made clear provisions regarding the distance between the car door sills and the accuracy of leveling.

[0003] GB / T 7588.1—2020, "Safety Code for Elevator Manufacturing and Installation Part 1: Passenger Elevators and Freight Elevators," stipulates: "5.3.4.1 The horizontal distance between the car sill and the landing sill shall not exceed 35 mm"; "5.12.1.1.4 The leveling accuracy of the car shall be ±10 mm. If the leveling accuracy exceeds ±20 mm (e.g., during loading and unloading), it shall be corrected to ±10 mm."

[0004] GB / T 10060—2023, "Elevator Installation and Acceptance Standard," stipulates: "5.6.2.5 Measure the horizontal distance between the car sill and the landing door sill. Within the effective door opening width, the deviation of this horizontal distance from the design value shall be 0~+3 mm, and the maximum value shall not exceed 35 mm."; "Test the leveling accuracy and leveling retention accuracy of the elevator car according to the method specified in GB / T 10059—2023, 5.2.3. The test results shall comply with the provisions of (GB / T 10058—2023, 4.3.7)."

[0005] When the elevator stops at a floor and opens the door, the car sill and the landing sill are often not perfectly aligned. During inspection, two steel rulers must be used together to measure the horizontal distance between the car sill and the landing sill and to ensure the accuracy of leveling. This process is cumbersome, time-consuming, labor-intensive, inconvenient to read data, and has a large reading error. Summary of the Invention

[0006] The purpose of this invention is to provide a tool for detecting elevator sill clearance and leveling accuracy, in order to solve the problems of cumbersome operation, time-consuming and labor-intensive operation, inconvenient data reading and large reading errors caused by the technical defects of existing detection tools.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0008] A tool for detecting elevator sill clearance and leveling accuracy includes:

[0009] A support frame, comprising a vertical rod, a support plate, and a guide frame, wherein the support plate is horizontally fixedly installed at the lower part of the vertical rod, the guide frame is horizontally fixedly installed at the upper part of the vertical rod, and a linkage group is slidably installed on the guide frame along the length direction of the guide frame, and a first stroke indicator mechanism is provided between the linkage group and the guide frame;

[0010] A sliding frame is vertically slidably mounted on a vertical rod. The sliding frame includes a frame body and support legs that are fixedly connected. A second stroke indicator mechanism is provided between the sliding frame and the support frame.

[0011] The outriggers and support plates are located on both sides of the vertical rod;

[0012] A sub-frame is vertically slidably mounted on a vertical rod and located below the frame body. A third elastic mechanism is provided between the frame body and the sub-frame.

[0013] A deflection frame, comprising a connector, a driving member, a driven member, a positioning member, and an arc-shaped rack;

[0014] The driving member and the driven member are parallel to each other and are both hinged to the vertical rod. The two ends of the positioning member are respectively hinged to the free ends of the driving member and the driven member and are parallel to the vertical rod.

[0015] The arc-shaped rack and the driving member are respectively fixedly installed at the upper and lower ends of the connector. The center of the arc-shaped rack is coaxial with the hinge axis of the driving member and the vertical rod. The linkage assembly is equipped with a rack that meshes with the arc-shaped rack.

[0016] The connecting member is connected to the sub-frame via a transmission. When the sub-frame moves downward along the vertical rod, it drives the driving member to rotate in the horizontal direction away from the support plate.

[0017] Further specifying, the connecting member is a rod that is inclined from top to bottom away from the support plate;

[0018] The subframe includes a sliding sleeve and rollers rotatably mounted on the sliding sleeve;

[0019] The roller rests against the side wall of the connector away from the support plate.

[0020] This structural design uses rollers to abut against the connectors made of inclined rods, thus completing the transmission connection between the connectors and the subframe. The mechanism is simple and inexpensive.

[0021] Furthermore, the radius of the pitch circle of the arc-shaped rack is greater than the center distance between the hinge axis of the driving member and the vertical rod, and between the hinge axis of the driving member and the positioning member.

[0022] This structural design, by limiting the radius of the pitch circle of the arc rack, enables the connecting part and the driving part to form a stroke amplification mechanism. With the rotation angle of the driving part remaining unchanged, the arc rack can drive the linkage group to slide a greater distance relative to the guide frame. This can increase the unit size on the first stroke indicating mechanism, thereby reducing the difficulty of observation, improving measurement accuracy, and making it highly practical.

[0023] Further specifying, a secondary rod is fixedly installed on the connector, and a strip-shaped channel for the roller to slide is formed between the secondary rod and the connector.

[0024] This structural design, through the setting of the auxiliary rod, allows the rollers to push the auxiliary rod in the opposite direction when the auxiliary frame moves upward, thereby driving the deflection frame to reset, making it highly practical.

[0025] Furthermore, a fourth elastic mechanism for driving the sub-frame to move upward is installed between the support frame and the sub-frame.

[0026] This structural design uses a fourth elastic mechanism to reset the subframe. When the testing tool needs to be removed, the roller pushes the sub-rod, causing the subframe to deflect the connecting parts. This allows the positioning parts to automatically disengage from the sill, making it easier to remove the lower end of the testing tool from between the two sills. This design is highly practical.

[0027] At the same time, the reset of the subframe driven by the fourth elastic mechanism can also be achieved by the reset of the sliding frame driven by the third elastic mechanism, making it convenient for the next use;

[0028] It also allows for a smaller distance between the positioning element and the vertical rod when the sliding frame is not pressed, making it easier for the lower end of the testing tool to be inserted into the gap between the two sills, thus making it more convenient to use.

[0029] Further defined, the linkage assembly includes a transmission component, a pushing block, a first sliding block, and a first one-way limiting component;

[0030] The guide frame is provided with a guide groove, and the transmission component and the first sliding block are both laterally slidably mounted on the guide frame;

[0031] The first stroke indicator mechanism is disposed between the guide frame and the first sliding block;

[0032] The push block is fixedly installed on the transmission component and is used to push the first sliding block to slide synchronously with the transmission component when the sliding frame moves downward;

[0033] The first unidirectional limiting member is installed between the guide frame and the first sliding block to limit the degree of freedom of the first sliding block to move toward the pushing block.

[0034] This structural design, through a linkage consisting of a transmission component, a push block, a first sliding block, and a first one-way limiting component, integrates the first stroke indicator mechanism between the guide frame and the first sliding block. This allows the transmission component, via the push block, to synchronously move the first sliding block laterally as the sliding frame is pressed downwards, causing relative movement between the guide frame and the first sliding block. This, in turn, drives the first stroke indicator mechanism to display the stroke value. Once in position, the first one-way limiting component creates a reverse limit on the first sliding block. Even if the sliding frame moves upwards and the deflection frame resets, the first sliding block cannot retract, ensuring a stable reading of the first stroke indicator mechanism. The value can still be directly read after the tool is removed, effectively improving operational convenience.

[0035] Furthermore, a first elastic mechanism is installed between the guide frame and the first sliding block;

[0036] The first elastic mechanism is used to drive the first sliding block to move closer to the pushing block.

[0037] This structural design, through the setting of the first elastic mechanism, allows the first one-way limiting member to be opened after the reading of the first stroke indicator mechanism is completed. The first elastic mechanism then pushes the first sliding block to achieve automatic reset of the first sliding block, making it more convenient to use.

[0038] Furthermore, the support frame also includes a second sliding block;

[0039] The sliding frame is provided with a sliding groove, and the second sliding block is vertically slidably installed in the sliding groove and located above the guide frame;

[0040] The second stroke indicator mechanism is disposed between the second sliding block and the frame;

[0041] A second one-way limiting member is also provided between the second sliding block and the frame, which is used to limit the degree of freedom of the second sliding block to move downward relative to the frame.

[0042] This structural design, through the cooperation of the second sliding block, slide groove, guide frame, second stroke indicator mechanism, and second one-way limiting component, ensures that when the sliding frame is pressed down, causing the outrigger to move downwards synchronously, the second sliding block, under the constraint of the guide frame, undergoes vertical relative displacement with the sliding frame, thereby driving the second stroke indicator mechanism to display the stroke value. After reaching the desired position, the second one-way limiting component forms a reverse limit on the second sliding block, so even if the sliding frame moves upwards, the relative position between the second sliding block and the frame does not change, and the measurement reading of the second stroke indicator mechanism can be stably maintained. The value can still be directly read after the tool is pulled out, effectively improving the ease of operation.

[0043] Further, the sliding frame also includes an extension frame, which is fixedly installed on the upper end of the frame body, and a support block is fixedly installed on the extension frame;

[0044] A second elastic mechanism is installed between the support block and the second sliding block, and the second elastic mechanism is used to push the second sliding block to move downward.

[0045] This structural design, through the setting of the second elastic mechanism, allows the second one-way limiting member to be opened after the reading of the second stroke indicator mechanism is completed. The second elastic mechanism then pushes the second sliding block to achieve automatic reset of the second sliding block, making it more convenient to use.

[0046] Furthermore, the support frame is equipped with a fourth elastic mechanism for resetting the deflection frame.

[0047] This structural design uses a fourth elastic mechanism to reset the deflection frame, so that when the testing tool needs to be removed, the positioning part can automatically disengage from the sill, making it easier for the lower end of the testing tool to be removed from between the two sills, which is highly practical.

[0048] At the same time, the resetting of the deflection frame driven by the fourth elastic mechanism can also drive the sub-frame to reset in the opposite direction, and then drive the sliding frame to reset via the third elastic mechanism, making it convenient for the next use;

[0049] It also allows for a smaller distance between the positioning element and the vertical rod when the sliding frame is not pressed, making it easier for the lower end of the testing tool to be inserted into the gap between the two sills, thus making it more convenient to use.

[0050] The invention employing the above technical solution has the following advantages:

[0051] 1. By pressing the sliding frame, the horizontal distance between the car sill and the landing sill, as well as the leveling accuracy, can be measured simultaneously. The operation is simple, the readings are accurate and convenient, and it is highly practical.

[0052] 2. The transmission connection between the connector and the subframe is completed by the rollers abutting against the connector made of inclined rods. The mechanism is simple and low in cost.

[0053] 3. By limiting the radius of the pitch circle of the arc rack, a stroke amplification mechanism is formed between the connecting part and the driving part. With the rotation angle of the driving part remaining unchanged, the arc rack can drive the linkage group to slide a greater distance relative to the guide frame. This can increase the unit size on the first stroke indicating mechanism, thereby reducing the difficulty of observation, improving the measurement accuracy, and making it highly practical.

[0054] 4. By setting up the auxiliary rod, when the auxiliary frame moves upward, the roller can push the auxiliary rod in the opposite direction, thereby driving the deflection frame to reset, which is highly practical.

[0055] 5. The subframe is reset by the fourth elastic mechanism, so that when the testing tool needs to be removed, the roller pushes the sub-rod, causing the subframe to deflect the connecting part, so that the positioning part can automatically disengage from the ground sill, and the lower end of the testing tool can be removed more easily from between the two ground sills, which is highly practical.

[0056] At the same time, the reset of the subframe driven by the fourth elastic mechanism can also be achieved by the reset of the sliding frame driven by the third elastic mechanism, making it convenient for the next use;

[0057] It also makes the distance between the positioning part and the vertical rod smaller when the sliding frame is not pressed, making it easier for the lower end of the testing tool to be inserted into the gap between the two sills, making it more convenient to use;

[0058] 6. A linkage group is formed by a transmission component, a push block, a first sliding block, and a first one-way limiting component. The first stroke indicator mechanism is integrated between the guide frame and the first sliding block. When the sliding frame is pressed down and the positioning component is brought into contact with the opposite sill, the transmission component drives the first sliding block to move laterally in sync via the push block. This causes relative movement between the guide frame and the first sliding block, which in turn drives the first stroke indicator mechanism to display the stroke value. After reaching the position, the first one-way limiting component forms a reverse limit on the first sliding block. Even if the sliding frame moves upward and the deflection frame resets, the first sliding block cannot retract. The measurement reading of the first stroke indicator mechanism can be stably maintained. The value can still be read directly after the tool is pulled out, which effectively improves the ease of operation.

[0059] 7. Through the cooperation of the second sliding block, slide groove, guide frame, second stroke indicator mechanism, and second one-way limiting member, when the sliding frame is pressed down and the outrigger moves down synchronously, the second sliding block undergoes vertical relative displacement with the sliding frame under the restriction of the guide frame, thereby driving the second stroke indicator mechanism to display the stroke value; after reaching the position, the second one-way limiting member forms a reverse limit on the second sliding block, so even if the sliding frame moves upward, the relative position between the second sliding block and the frame does not change, and the measurement reading of the second stroke indicator mechanism can be stably maintained. The value can still be read directly after the tool is pulled out, effectively improving the ease of operation. Attached Figure Description

[0083] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0084] like Figures 1-12 As shown, the present invention provides a tool for detecting elevator sill clearance and leveling accuracy, comprising:

[0085] Support frame 1 includes a vertical rod 11, a support plate 12 and a guide frame 13. The support plate 12 is horizontally fixedly installed on the lower part of the vertical rod 11, and the guide frame 13 is horizontally fixedly installed on the upper part of the vertical rod 11. A linkage group 14 is slidably installed on the guide frame 13 along the length direction of the guide frame 13. A first stroke indicator mechanism is provided between the linkage group 14 and the guide frame 13.

[0086] The sliding frame 2 is vertically slidably mounted on the vertical rod 11. The sliding frame 2 includes a frame body 21 and a support leg 22 that are fixedly connected. A second stroke indicator mechanism is provided between the sliding frame 2 and the support frame 1.

[0087] The outrigger 22 and the support plate 12 are located on both sides of the vertical rod 11;

[0088] Sub-frame 3 is vertically slidably mounted on vertical rod 11 and located below frame body 21. A third elastic mechanism 53 is provided between frame body 21 and sub-frame 3.

[0089] The deflection frame 4 includes a connector 41, a driving member 42, a driven member 43, a positioning member 44, and an arc-shaped rack 45.

[0090] The driving member 42 and the driven member 43 are parallel to each other and are both hinged to the vertical rod 11. The two ends of the positioning member 44 are respectively hinged to the free ends of the driving member 42 and the driven member 43 and are parallel to the vertical rod 11.

[0091] The arc-shaped rack 45 and the driving member 42 are fixedly installed at the upper and lower ends of the connector 41, respectively. The center of the arc-shaped rack 45 is coaxial with the hinge axis of the driving member 42 and the vertical rod 11. A rack that meshes with the arc-shaped rack 45 is installed on the linkage assembly 14.

[0092] The connecting piece 41 is connected to the sub-frame 3 via a transmission. When the sub-frame 3 moves downward along the vertical rod 11, it drives the driving piece 42 to rotate in the horizontal direction away from the support plate 12.

[0093] When in use, insert the lower end of the vertical rod 11 between the car sill and the landing door sill until the support plate 12 is in contact with the upper surface of one of the sills. At this time, the positioning piece 44 is also located between the car sill and the landing door sill.

[0094] The sliding frame 2 is moved downward relative to the support frame 1, and the sub-frame 3 is driven to move downward through the third elastic mechanism 53. The transmission connection between the sub-frame 3 and the connecting member 41 drives the driving member 42 to rotate. The parallel four-bar linkage composed of the driving member 42, the driven member 43, the positioning member 44 and the vertical rod 11 deflects synchronously, so that the positioning member 44 moves horizontally toward another sill until the lower end of the vertical rod 11 and the positioning member 44 abut against the side walls of the two sills respectively.

[0095] During the rotation of the driving member 42, the arc-shaped rack 45 rotates around the hinge axis of the driving member 42 and the vertical rod 11, thereby causing the linkage group 14 to slide relative to the guide frame 13.

[0096] Then, the sliding frame 2 continues to move downward relative to the support frame 1. At this time, the reaction force provided by the two sills prevents the sub-frame 3 from moving downward, so that the reading of the first stroke indicator mechanism no longer changes. Only the sliding frame 2 continues to move downward until the lower end face of the support leg 22 is in contact with the upper end face of the other sill.

[0097] At this point, the horizontal distance between the car sill and the landing sill can be obtained by reading the reading of the first travel indicator mechanism;

[0098] By reading the readings of the second travel indicator, the leveling accuracy of the car sill and landing sill can be determined.

[0099] The sliding frame 2 also includes a handle 20 that is horizontally fixedly installed on the upper end of the frame 21.

[0100] In practice, depending on the actual situation, the handle 20 can be omitted and the frame 21 can be operated directly. In this embodiment, the sliding frame 2 is operated through the handle 20, which makes it more convenient to use.

[0101] The first travel indicator mechanism includes a first scale and a first pointer 61;

[0102] The first scale is marked on the linkage assembly 14, and the first pointer 61 is fixedly mounted on the guide frame 13.

[0103] In practice, depending on the actual situation, the first stroke indicator mechanism can be set as a pressure sensor located between the linkage group 14 and the guide frame 13, and then buffered with an elastic element. The distance dimension can be obtained from the reading of the pressure sensor. In this embodiment, the first stroke indicator mechanism is formed by the first scale engraved on the linkage group 14 and the first pointer 61 fixedly set on the guide frame 13. The structure is simple, the cost is low, and the practicality is strong.

[0104] The second travel indicator mechanism includes a second scale and a second pointer 62;

[0105] The second scale is marked on the support frame 1, and the second pointer 62 is fixedly set on the sliding frame 2.

[0106] In practice, depending on the actual situation, the second stroke indicator mechanism can also be set as a pressure sensor located between the support frame 1 and the sliding frame 2, and then buffered with an elastic element. The distance dimension can be obtained from the reading of the pressure sensor. In this embodiment, the second stroke indicator mechanism is formed by the second scale engraved on the support frame 1 and the second pointer 62 fixedly set on the sliding frame 2. The structure is simple, the cost is low, and the practicality is strong.

[0107] The connector 41 is a rod that is inclined from top to bottom away from the support plate 12;

[0108] Subframe 3 includes a sliding sleeve 31 and a roller 32 rotatably mounted on the sliding sleeve 31;

[0109] The roller 32 rests against the side wall of the connector 41 away from the support plate 12.

[0110] In practice, depending on the actual situation, the connecting member 41 can be set as a gear and the rack can be set on the sub-frame 3. The transmission connection between the connecting member 41 and the sub-frame 3 is completed by the meshing of the gear and the rack. In this embodiment, the transmission connection between the connecting member 41 and the sub-frame 3 is completed by the roller 32 abutting against the connecting member 41, which is composed of an inclined rod. The mechanism is simple and the cost is low.

[0111] The radius of the pitch circle of the arc rack 45 is greater than the center distance between the hinge axis of the driving member 42 and the vertical rod 11, and between the hinge axis of the driving member 42 and the positioning member 44.

[0112] In practice, the dimensions of the two can be set to be equal according to the actual situation. In this embodiment, by limiting the radius of the pitch circle of the arc rack 45, the connecting member 41 and the driving member 42 form a stroke amplification mechanism. When the rotation angle of the driving member 42 remains unchanged, the arc rack 45 can drive the linkage group 14 to slide a greater distance relative to the guide frame 13. This can expand the unit size on the first stroke indicator mechanism, thereby reducing the difficulty of observation, improving the measurement accuracy, and making it highly practical.

[0113] A secondary rod 411 is fixedly installed on the connector 41, and a strip channel 410 for the roller 32 to slide is formed between the secondary rod 411 and the connector 41.

[0114] In fact, depending on the actual situation, the auxiliary rod 411 can be omitted, and the deflection frame 4 can be manually reset directly. In this embodiment, by setting the auxiliary rod 411, when the auxiliary frame 3 moves upward, the roller 32 can push the auxiliary rod 411 in the opposite direction, thereby driving the deflection frame 4 to reset, which is highly practical.

[0115] A fourth elastic mechanism 54 is installed between the support frame 1 and the sub-frame 3 to drive the sub-frame 3 to move upward.

[0116] The fourth elastic mechanism 54 is preferably a compression spring installed between the support frame 1 and the sub-frame 3, or a tension spring installed between the support frame 1 and the sub-frame 3.

[0117] In practice, depending on the actual situation, the fourth elastic mechanism 54 can be omitted, and the sub-frame 3 can be reset manually. In this embodiment, the sub-frame 3 is reset by the fourth elastic mechanism 54, so that when the detection tool needs to be removed, the roller 32 pushes the sub-rod 411, causing the sub-frame 3 to drive the connecting piece 41 to deflect, so that the positioning piece 44 can automatically disengage from the ground sill, thereby making it easier for the lower end of the detection tool to be removed from between the two ground sills, which is highly practical.

[0118] At the same time, the reset of the sub-frame 3 driven by the fourth elastic mechanism 54 can also be reset by the sliding frame 2 driven by the third elastic mechanism 53, making it convenient for the next use;

[0119] It also makes the distance between the positioning element 44 and the vertical rod 11 smaller when the sliding frame 2 is not pressed, making it easier for the lower end of the testing tool to be inserted into the gap between the two sills, making it more convenient to use.

[0120] The linkage assembly 14 includes a transmission component 141, a push block 1410, a first sliding block 142, and a first one-way limiting component 143;

[0121] The guide frame 13 is provided with a guide groove, and the transmission component 141 and the first sliding block 142 are both laterally slidably mounted on the guide frame 13;

[0122] The first stroke indicator mechanism is located between the guide frame 13 and the first sliding block 142;

[0123] The push block 1410 is fixedly installed on the transmission component 141 and is used to push the first sliding block 142 to slide synchronously with the transmission component 141 when the sliding frame 2 moves downward;

[0124] The first one-way limiting member 143 is installed between the guide frame 13 and the first sliding block 142 to limit the degree of freedom of the first sliding block 142 to move toward the push block 1410.

[0125] In practice, depending on the actual situation, the linkage group 14 can be set as an integral unit, and the reading can be taken directly after pressing down. In this embodiment, the linkage group 14 is composed of the transmission component 141, the push block 1410, the first sliding block 142 and the first one-way limiting component 143, and the first stroke indicator mechanism is integrated between the guide frame 13 and the first sliding block 142. When the sliding frame 2 is pressed down and the positioning component 44 is attached to the opposite sill, the transmission component 141 drives the first sliding block 142 to move laterally in sync via the push block 1410, so that the guide frame 13 and the first sliding block 142 move relative to each other, thereby driving the first stroke indicator mechanism to display the stroke value. After the position is reached, the first one-way limiting component 143 forms a reverse limit on the first sliding block 142. Even if the sliding frame 2 moves upward and the deflection frame 4 is reset, the first sliding block 142 cannot retract. The measurement reading of the first stroke indicator mechanism can be stably maintained. The value can still be read directly after the tool is pulled out, which effectively improves the ease of operation.

[0126] The first travel indicator mechanism includes a first scale and a first pointer 61;

[0127] The first scale is marked on the first sliding block 142, and the first pointer 61 is fixedly mounted on the guide frame 13.

[0128] In practice, depending on the actual situation, the first stroke indicator mechanism can also be set as a pressure sensor located between the first sliding block 142 and the guide frame 13, and then buffered with an elastic element. The distance dimension can be obtained from the reading of the pressure sensor. In this embodiment, the first stroke indicator mechanism is formed by the first scale engraved on the first sliding block 142 and the first pointer 61 fixedly set on the guide frame 13. The first stroke indicator mechanism displays the relative position between the first sliding block 142 and the guide frame 13, thereby obtaining the distance difference between the outer wall of the vertical rod 11 and the outer wall of the positioning member 44, so as to complete the horizontal distance measurement between the car sill and the landing sill. The structure is simple, the cost is low, and the practicality is strong.

[0129] The first one-way limiting member 143 includes a first torsion spring and a first top block 1430;

[0130] The first top block 1430 is rotatably mounted on the guide frame 13;

[0131] The first torsion spring is installed between the first top block 1430 and the guide frame 13;

[0132] The first top block 1430 tilts from top to bottom away from the push block 1410 under the action of the first torsion spring and abuts against the upper end face of the first sliding block 142.

[0133] In fact, depending on the actual situation, the first one-way limiting member 143 can also be set as a one-way ratchet. In this embodiment, the first one-way limiting member 143, which is composed of the first torsion spring and the first top block 1430, completes the restriction of the degree of freedom of movement of the first sliding block 142 relative to the guide frame 13. The structure is simple, the cost is low, and the practicality is strong.

[0134] A first elastic mechanism 51 is installed between the guide frame 13 and the first sliding block 142;

[0135] The first elastic mechanism 51 is used to drive the first sliding block 142 to move towards the push block 1410.

[0136] In practice, depending on the actual situation, the first elastic mechanism 51 can be omitted, and the first sliding block 142 can be reset manually. In this embodiment, by setting the first elastic mechanism 51, after the reading of the first stroke indicator mechanism is completed, the first one-way limit member 143 is opened, and the first elastic mechanism 51 pushes the first sliding block 142 to realize the automatic reset of the first sliding block 142, which is more convenient to use.

[0137] The support frame 1 also includes a second sliding block 15;

[0138] The sliding frame 2 has a sliding groove, and the second sliding block 15 is vertically slidably installed in the sliding groove and located above the guide frame 13;

[0139] The second stroke indicator mechanism is located between the second sliding block 15 and the frame 21;

[0140] A second one-way limiting member 16 is also provided between the second sliding block 15 and the frame 21. The second one-way limiting member 16 is used to limit the degree of freedom of the second sliding block 15 to move downward relative to the frame 21.

[0141] In practice, depending on the actual situation, the second stroke indicator mechanism can be directly set between the frame 21 and the guide frame 13, and the reading can be taken directly after pressing down. In this embodiment, through the cooperation of the second sliding block 15, the slide groove, the guide frame 13, the second stroke indicator mechanism, and the second one-way limiting member 16, the second sliding block 15 undergoes a vertical relative displacement with the sliding frame 2 under the restriction of the guide frame 13 during the process of pressing down on the sliding frame 2 and driving the support leg 22 to move downward synchronously. This drives the second stroke indicator mechanism to display the stroke value. After reaching the position, the second one-way limiting member 16 forms a reverse limit on the second sliding block 15. Even if the sliding frame 2 moves upward, the relative position between the second sliding block 15 and the frame 21 does not change, and the measurement reading of the second stroke indicator mechanism can be stably maintained. The value can still be read directly after the tool is pulled out, which effectively improves the ease of operation.

[0142] The second travel indicator mechanism includes a second scale and a second pointer 62;

[0143] The second scale is marked on the second sliding block 15, and the second pointer 62 is fixedly set on the frame 21.

[0144] In practice, depending on the actual situation, the second stroke indicator mechanism can also be set as a pressure sensor located between the second sliding block 15 and the frame 21, and then buffered with an elastic element. The distance dimension can be obtained from the reading of the pressure sensor. In this embodiment, the second stroke indicator mechanism is formed by the second scale engraved on the second sliding block 15 and the second pointer 62 fixedly set on the frame 21. The second stroke indicator mechanism displays the relative position between the second sliding block 15 and the frame 21, thereby obtaining the height difference between the support plate 12 and the support leg 22, so as to complete the leveling accuracy measurement of the car sill and the landing sill. The structure is simple, the cost is low, and the practicality is strong.

[0145] The second one-way limiting member 16 includes a second torsion spring and a second top block 160;

[0146] The second top block 160 is rotatably mounted on the frame 21;

[0147] The second torsion spring is installed between the second top block 160 and the frame 21;

[0148] The second top block 160, under the action of the second torsion spring, tilts from top to bottom away from the second sliding block 15 and abuts against the upper end surface of the second sliding block 15.

[0149] In practice, depending on the actual situation, the second one-way limiting member 16 can also be set as a one-way ratchet. In this embodiment, the second one-way limiting member 16, which is composed of the second torsion spring and the second top block 160, completes the restriction of the second sliding block 15's degree of freedom of movement relative to the frame 21. The structure is simple, the cost is low, and the practicality is strong.

[0150] The sliding frame 2 also includes an extension frame 23, which is fixedly installed on the upper end of the frame 21, and a support block 230 is fixedly installed on the extension frame 23;

[0151] A second elastic mechanism 52 is installed between the support block 230 and the second sliding block 15. The second elastic mechanism 52 is used to push the second sliding block 15 downward.

[0152] In practice, depending on the actual situation, the second elastic mechanism 52 can be omitted, and the second sliding block 15 can be reset manually. In this embodiment, by setting the second elastic mechanism 52, after the reading of the second stroke indicator mechanism is completed, the second one-way limit member 16 is opened, and the second elastic mechanism 52 pushes the second sliding block 15 to realize the automatic reset of the second sliding block 15, which is more convenient to use.

[0153] A fourth elastic mechanism 54 for resetting the deflection frame 4 is installed on the support frame 1. The fourth elastic mechanism 54 is preferably a torsion spring installed between the connecting member 41 and the vertical rod 11, or a tension spring installed between the vertical rod 11 and the positioning member 44.

[0154] In fact, depending on the actual situation, the fourth elastic mechanism 54 can be omitted, and the deflection frame 4 can be reset manually. In this embodiment, the deflection frame 4 is reset by the fourth elastic mechanism 54, so that when the detection tool needs to be removed, the positioning part 44 can automatically disengage from the ground sill, so that the lower end of the detection tool can be removed more easily from between the two ground sills, which is more practical.

[0155] At the same time, the resetting of the deflection frame 4 driven by the fourth elastic mechanism 54 can also drive the sub-frame 3 to reset in the opposite direction, and then drive the sliding frame 2 to reset via the third elastic mechanism 53, so as to facilitate the next use.

[0156] It also makes the distance between the positioning element 44 and the vertical rod 11 smaller when the sliding frame 2 is not pressed, making it easier for the lower end of the testing tool to be inserted into the gap between the two sills, making it more convenient to use.

[0157] In this embodiment, during use, the lower end of the vertical rod 11 is inserted between the car sill and the landing sill by holding the handle 20 until the support plate 12 is in contact with the upper surface of one of the sills. At this time, the positioning member 44 is also located between the car sill and the landing sill. Figure 1 , Figure 5 and Figure 6 As shown;

[0158] Then, by pressing the sliding frame 2 downward relative to the support frame 1 through the handle 20, the sub-frame 3 is driven downward through the third elastic mechanism 53. Utilizing the contact transmission between the roller 32 on the sub-frame 3 and the connecting piece 41, the driving member 42 rotates clockwise. The parallel four-bar linkage composed of the driving member 42, driven member 43, positioning member 44, and vertical rod 11 deflects synchronously, causing the positioning member 44 to move horizontally towards another sill until the lower end of the vertical rod 11 and the positioning member 44 respectively abut against the side walls of the two sills. At this point, the outrigger 22 is not in contact with the sill. Figure 7 , Figure 8 and Figure 9 As shown;

[0159] During the rotation of the active member 42, the arc-shaped rack 45 rotates clockwise around the hinge axis of the active member 42 and the vertical rod 11, thereby driving the transmission member 141 and the push block 1410 to slide laterally to the right along the guide frame 13, pushing the first sliding block 142 to move synchronously and compress the first elastic mechanism 51, driving the first stroke indicator mechanism to display the stroke value.

[0160] After the positioning component 44 is in place, the first one-way limiting component 143 forms a reverse lock on the first sliding block 142, so that the reading of the first stroke indicator mechanism remains stable.

[0161] Then, the sliding frame 2 continues to move downward relative to the support frame 1. At this time, the reaction force provided by the two sills prevents the sub-frame 3 from moving downward further, and the reading of the first stroke indicator mechanism no longer changes. Only the sliding frame 2 continues to move downward, causing the second sliding block 15 to undergo vertical displacement relative to the frame 21, driving the second stroke indicator mechanism to display the stroke value, until the lower end face of the support leg 22 is in contact with the upper end face of the other sill. Figure 10 As shown;

[0162] Once in position, the second one-way limiting member 16 forms a reverse lock on the second sliding block 15, keeping the reading of the second stroke indicator mechanism stable;

[0163] At this point, the testing tool can be pulled out of the sill gap via handle 20. By reading the first scale corresponding to the first pointer 61 locked by the first one-way limiting member 143, the horizontal distance between the car sill and the landing sill can be obtained. By reading the second scale corresponding to the second pointer 62 locked by the second one-way limiting member 16, the leveling accuracy between the car sill and the landing sill can be obtained. After the measurement is completed, the one-way limiting lock is released, and each component automatically resets under the action of the corresponding elastic mechanism, making it convenient for the next use.
