For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] Combine the following Figure 1-Figure 27 The free-climbing device of the present invention is described.

[0050] The present invention provides a climbing-free device, such as Figures 1 to 27As shown, it includes a car 100, a door 200, an upper contour plate 300, a lower contour plate 400, a first closure detection assembly 210, a second closure detection assembly 310 and a controller 700. The door 200 is installed on one side of the car 100, and the first closure detection assembly 210 is used to detect the closed state of the door 200. The upper contour plate 300 can be opened and closed and installed on the top of the car 100, and the second closure detection assembly 310 is used to detect the closed state of the upper contour plate 300. The lower contour plate 400 can be opened and closed and installed on the bottom of the car 100. The first closure detection assembly 210 and the second closure detection assembly 310 are both connected to the controller 700 for communication.

[0051] The door 200 can be slidably mounted on the car 100 or hinged on the car 100, as long as it can be opened and closed to provide a passage for the operator to go up and down. The first closure detection component 210 can detect the closed state of the door 200. Before responding to the operation instruction input by the user, the controller 700 first determines whether the current door 200 is closed based on the detection value of the first closure detection component 210. It will respond to the operation instruction input by the user only when the door 200 is in a closed state, so as to prevent the operator from forgetting to close the door 200 and improve the safety factor. It is understandable that when the controller 700 receives the user's operation instruction, if it determines that the door 200 is not closed, it controls the alarm to send an alarm message to remind the operator.

[0052] The car 100 is the main body of the anti-climbing device and has the function of protecting the operator. Figures 1 to 7 As shown, the car 100 includes a crossbeam 110, a longitudinal beam 130 and an equipment plate 111. The crossbeam 110 and the longitudinal beam 130 are connected and surrounded to form a car frame, and the equipment plate 111 is fixed to the car frame. Figures 6 to 8 As shown, a handrail 123 is provided on the side of the equipment plate 111 facing the inside of the car 100; there are two handrails 123, which are arranged in parallel. A guard plate is installed on the car frame, and the guard plate and the equipment plate 111 are surrounded to form a relatively closed car body. A guide wheel assembly 730 for slidingly cooperating with the lifting guide rail is installed on the side of the equipment plate 111 facing the outside of the car 100. Figure 5 and Figure 6 As shown, the guide wheel assembly is provided with eight groups. Figures 5 to 7 As shown, the side of the equipment board 111 facing the inside of the car 100 is provided with a controller 700, a battery 750 and a vehicle-mounted transmitter 720. The vehicle-mounted transmitter 720 is used to realize information exchange between the controller 700 and the ground control equipment. The battery 750 is electrically connected to the controller 700 and the vehicle-mounted transmitter 720 to supply power to the power-consuming devices. Figure 5 and Figure 6As shown, the car 100 is provided with an upward deceleration switch 701, an upward limit switch 702 and a control handrail 703, and the upward deceleration switch 701, the upward limit switch 702 and the control handrail 703 are all connected to the controller 700. The operator controls the non-climbing device to decelerate upward when approaching the working position by operating the upward deceleration switch 701, and controls the non-climbing device to stop upward when reaching the upward limit position by operating the upward limit switch 702. The control handrail 703 is an operating lever, and the operator can input corresponding control instructions to the non-climbing device through the control handrail 703.

[0053] like Figure 5 As shown, in order to prevent the guide wheel assembly 730 from being separated from the lifting guide rail, the car 100 is also provided with an anti-falling assembly 740. Optionally, the anti-falling assembly 740 includes a wedge block, which cooperates with the wedge-shaped lifting guide rail to prevent the lifting guide rail from being loosened from the car 100 during operation. Figure 6 As shown, in order to prevent the car 100 from suddenly accelerating and falling, an anti-falling assembly 731 is provided on the equipment plate 111. The anti-falling assembly 731 includes a locking block that can be locked with the traction rope 900 and a speed detector for detecting the running speed of the car 100. When the speed detector detects that the car 100 suddenly accelerates, the locking block locks the traction rope 900 to prevent it from falling.

[0054] Specifically, the car 100 includes a bottom frame 112, a left front longitudinal beam 113, a left rear longitudinal beam 115, a right front longitudinal beam 114, a right rear longitudinal beam 116, a left top cross beam 117, a right top cross beam 118 and a middle cross beam 119. The bottoms of the left front longitudinal beam 113, the left rear longitudinal beam 115, the right front longitudinal beam 114 and the right rear longitudinal beam 116 are connected to the bottom frame 112 by bolts, and the tops are connected to the left top cross beam 117, the right top cross beam 118 and the middle cross beam 119 by bolts. Guard plates are installed on the three sides of the car 100 where the equipment plate 111 is not provided. Specifically, the guard plates include a left guard plate 120, a right guard plate 121 and a rear guard plate 122. The left guard plate 120 is provided on the left side of the car 100, the right guard plate 121 is provided on the right side of the car 100, and the rear guard plate 122 is provided on the rear side of the car 100. It should be noted that the front, rear, left and right sides are based on the orientation when the operator stands in the car 100 and faces the operating console.

[0055] The upper profile plate 300 is installed on the left top cross beam 117, the right top cross beam 118 and the middle cross beam 119, and can be opened from the inside of the car 100 to form a passage for people to pass upward. In order to prevent the upper profile plate 300 from being not closed during the operation of the car 100, a second closing detection component 310 is provided to detect whether the upper profile plate 300 is closed. The controller 700 can issue an alarm according to the detection result of the second closing detection component 310, thereby improving the safety protection level.

[0056] The lower profile plate 400 can be opened and closed and installed on the bottom frame 112. After the lower profile plate 400 is opened, a rescue passage can be formed. Under normal circumstances, the lower profile plate 400 is in a closed state; only when an accident occurs, the lower profile plate 400 is opened from the outside of the car 100 to provide a passage for the rescue operator in the car 100. Fig.15 The lower profile plate 400 is mounted on the bottom frame 112 through two sets of torsion spring hinge assemblies 401. The lower profile plate 400 is locked on the bottom frame 112 through the cooperation of the plum nut 402 and the pressure rivet screw 403. After the plum nut 402 is loosened, the lower profile plate 400 is automatically opened under the action of the torsion spring built into the torsion spring hinge, exposing the lower personnel passage.

[0057] The anti-climbing device provided in the embodiment of the present invention has a car 100 as the main body, which provides safety protection for the operator from all sides. The car door 200 installed on the car 100 can provide an entry passage for the operator, and the opening of the upper contour plate 300 can provide an upward passage for the operator. At the same time, a first closing detection component 210 and a second closing detection component 310 are provided to monitor the closing state of the car door 200 and the closing state of the upper contour plate 300, so as to avoid the car door 200 and the upper contour plate 300 being unlocked before the anti-climbing device is started, thereby improving the operation safety.

[0058] like Fig. 9 As shown, the elevator car 100 has a first guide rail 201 and a second guide rail 202 arranged in parallel, and the opposite sides of the door 200 are respectively slidably mounted on the first guide rail 201 and the second guide rail 202 along the longitudinal direction. The door 200 is provided with a first locking portion 207, and the elevator car 100 is provided with a second locking portion 208. Fig.10 As shown, when the door 200 is in a closed state, the first locking portion 207 cooperates with the second locking portion 208 to fix the position of the door 200 relative to the car 100. The first closing detection component 210 is installed on the first locking portion 207 or the second locking portion 208, and is used to generate a trigger signal when the first locking portion 207 and the second locking portion 208 are in a locked state.

[0059] The first guide rail 201 is fixed to the left front longitudinal beam 113 by bolts, and the second guide rail 202 is fixed to the left rear longitudinal beam 115 by bolts. The first guide rail 201 and the second guide rail 202 provide guidance for the up and down movement of the door 200. Compared with the door 200 hinged to the car 100, the door 200 slidably mounted on the car 100 can save space when opening and closing, and because both sides of the door 200 are always connected to the car 100, it can prevent the door 200 from being opened by external force, thereby maintaining good protection performance.

[0060] like Fig.10As shown, the first locking portion 207 is a latch slidably mounted on the door 200, and the second locking portion 208 is a pin hole. When the door 200 slides to the closed position along the first guide rail 201 and the second guide rail 202, the first locking portion 207 is opposite to the second locking portion 208, and the latch can be inserted into the lock hole to lock the door 200. Optionally, the first closure detection component 210 is a trigger switch, which is installed in the pin hole. After the latch is inserted into the pin hole, the first closure detection component 210 generates a trigger signal. The controller 700 determines that the door 200 is in a closed state based on the trigger signal. Correspondingly, if the first closure detection component 210 does not generate a trigger signal before startup, the door 200 is in an open state.

[0061] It is understandable that the compartment door 200 can be a single-door sliding type or a double-door sliding type.

[0062] In a specific embodiment, if Figure 1 and Fig. 9 As shown, the compartment door 200 includes a first sliding door 203 and a second sliding door 204. The first sliding door 203 is slidably mounted on the first and second sliding rails on opposite sides in the longitudinal direction, and the second sliding door 204 is slidably mounted on the first and second sliding rails on opposite sides in the longitudinal direction. The first sliding door 203 and the second sliding door 204 move synchronously and in opposite directions. The first sliding door 203 and the second sliding door 204 slide relative to each other up and down, and the structure mode of opening and closing in opposite directions can provide a larger entrance channel with a smaller sliding space, thereby reducing the setting of the sliding area.

[0063] The first locking portion 207 is located on the first sliding door 203, and the first sliding door 203 and the second sliding door 204 are constrained to move upward and downward by the limiting structure. Specifically, the anti-climbing device further includes a roller 205 and a suspension rope 206, and the roller 205 is rotatably mounted on the car 100. One end of the suspension rope 206 is connected to the first sliding door 203, and the other end of the suspension rope 206 is connected to the second sliding door 204 by passing around the roller 205.

[0064] Optionally, the suspension rope 206 is a steel wire rope, which has high strength and high safety. Fig. 9, two rollers 205 are installed on the left top crossbeam 117 and are spaced apart. The two rollers 205 are arranged corresponding to the first guide rail 201 and the second guide rail 202 and are located above the first guide rail 201 and the second guide rail 202. A suspension rope 206 is set on the two rollers 205, one end of which is connected to the right side of the first sliding door 203, and the other end is connected to the left side of the second sliding door 204. When the first sliding door 203 moves up, the second sliding door 204 moves down synchronously; when the first sliding door 203 moves down, the second sliding door 204 moves up. Under the action of the suspension rope 206, the first sliding door 203 and the second sliding door 204 move in opposite directions, and the distance between the first sliding door 203 and the second sliding door 204 can be adjusted.

[0065] like Figures 11 to 14 As shown, an upper fixing plate 301 is installed on the top of the car 100, and the upper contour plate 300 is hinged to the upper fixing plate 301. The upper fixing plate 301 provides an installation position for the upper contour plate 300. The upper contour plate 300 has a first lock body 302, and the upper fixing plate 301 is provided with a second lock body 303. When the upper contour plate 300 covers the upper fixing plate 301, the first lock body 302 and the second lock body 303 can cooperate with each other to lock the position of the upper contour plate 300 and the upper fixing plate 301. The second closing detection component 310 is used to generate a trigger signal when the upper contour plate 300 covers the upper fixing plate 301.

[0066] Optionally, the first lock body 302 is a latch and the second lock body 303 is a lock buckle. When the upper profile plate 300 covers the upper fixing plate 301, the first lock body 302 and the second lock body 303 are opposite to each other, and the latch can be inserted into the lock buckle to lock the upper profile plate 300. Fig.13 As shown, the upper contour plate 300 is provided with two first lock bodies 302, and correspondingly, the upper fixing plate 301 is provided with second lock bodies 303 on both opposite sides. The upper fixing plate 301 includes three plates connected in sequence, and the three plates are connected to the left top cross beam 117, the right top cross beam 118 and the middle cross beam 119 by screws one by one. Fig.13 As shown, the upper profile plate 300 is installed on the upper fixed plate 301 through a hinge, and the upper profile plate 300 can be turned up as a door for people to pass through. When the upper profile plate 300 is in a closed state, the upper profile plate 300 is locked and installed on the upper fixed plate 301 through the cooperation of the first lock body 302 and the second lock body 303.

[0067] like Fig.13 As shown, the second closing detection component 310 is a micro switch, which is fixed to the hinge side of the upper fixing plate 301 through the first switch bracket 311. After the upper contour plate 300 is closed, the lower surface of the upper contour plate 300 triggers the micro switch and sends an electrical signal. The controller 700 confirms that the upper contour plate 300 has been closed according to the electrical signal of the micro switch, which serves as a precondition for the start of the anti-climbing device.

[0068] The upper fixed plate 301 can be raised and lowered and installed on the top of the car 100. When the climbing-free device encounters an obstacle while ascending, the upper fixed plate 301 moves toward the top of the car 100. The climbing-free device also includes an upward obstacle detection component 500, which is in communication connection with the controller 700. The upward obstacle detection component 500 is used to generate a trigger signal when the upper fixed plate 301 encounters an obstacle and moves to a preset position in the direction close to the top of the car 100. In addition, the upper fixed plate 301 can also be fixed on the top of the car 100 to seal the top of the car 100. A reversible rod body is provided on the outside of the upper fixed plate 301, and the rod body flips after encountering an obstacle to trigger the upward obstacle detection component 500.

[0069] The upward obstacle detection component 500 is a trigger switch. A second switch bracket 510 is provided on at least one of the left top beam 117, the right top beam 118 and the middle beam 119. A trigger switch is installed on each second switch bracket 510. The trigger switch is triggered from top to bottom. Fig.11 and Fig.12 As shown, a second switch bracket 510 is provided in the middle of the left top crossbeam 117 and the right top crossbeam 118. The second switch bracket 510 is an L-shaped plate, one of which is attached to the crossbeam 110 and fixed to the crossbeam 110 by screws or other fixing structures, and the other is fixedly connected to the uplink obstacle detection assembly 500. Specifically, as Fig.11 and Fig.12 As shown, each upward obstacle detection assembly 500 is connected to the corresponding second switch bracket 510 through two sets of hexagonal flat round head screws, washers and hexagonal nuts. The upper fixing plate 301 moves downward after encountering an obstacle, triggering the upward obstacle detection assembly 500 installed on the second switch bracket 510 to output an electrical signal. The controller 700 determines that the upper contour plate 300 encounters an obstacle based on the electrical signal.

[0070] Specifically, the anti-climbing device further includes a support rod 501 and an elastic member 502 sleeved on the support rod 501, one end of the support rod 501 is plugged and fixed to the top of the car 100, the other end of the support rod 501 has an end cap, the upper fixing plate 301 can be slidably mounted on the support rod 501, and the elastic member 502 is sandwiched between the upper fixing plate 301 and the top of the car 100. Optionally, the elastic member 502 is a compression spring.

[0071] Refer to the attached Figures 11 to 14 The left top cross beam 117 and the right top cross beam 118 are provided with support rods 501 at the front and rear ends respectively, and an elastic member 502 is sleeved on each support rod 501. The left top cross beam 117 and the right top cross beam 118 are provided with through holes, such as Fig.14As shown, the support tube 504 is arranged between the opposite surfaces of the cross beam 110 for support, and flat washers 503 are respectively arranged on the upper and lower sides of the cross beam 110. The support rod 501 passes through a through hole, the support tube 504, and another through hole and is locked with the locking nut 505, one of the flat washers 503 is located at the locking position of the locking nut 505, and the other flat washer 503 is located at the bottom of the elastic member 502. The upper fixed plate 301 can be slidably sleeved on the support rod 501, one end of the elastic member 502 is against the flat washer 503, and the other end is against the upper fixed plate 301. In the case of no obstacles, the elastic member 502 presses the upper fixed plate 301 against the end cap of the support rod 501. In the case of encountering obstacles, the upper fixed plate 301 moves down along the support rod 501, compresses the elastic member 502, and triggers the upward obstacle detection component 500 located at the top of the car 100 to realize obstacle detection in the upward direction.

[0072] In addition, the upper fixing plate 301 can also be installed on the top of the car 100 in a liftable manner by using a telescopic rod or other structures.

[0073] like Fig.18 and Fig.19 As shown, the anti-climbing device also includes a sensing rod 601, a stop plate 602 and a downward obstacle detection component 600, the sensing rod 601 is fixedly connected to the stop plate 602, and the stop plate 602 is rotatably connected to the bottom of the car 100. Fig.23 As shown, the stop plate 602 has a stop surface 603, and the stop surface 603 can fit with the bottom of the car 100 so that the sensing rod 601 is tilted relative to the bottom of the car 100. Fig.19 and Fig. 20 As shown, the downlink obstacle detection component 600 is used to generate a trigger signal when the sensing rod 601 encounters an obstacle, and the downlink obstacle detection component 600 is communicatively connected with the controller 700.

[0074] Refer to the attached Fig.19 and attached Fig. 20 , the down-going obstacle detection assembly 600 is fixed to the bottom of the car 100, specifically, fixed to the bottom frame 112. The down-going obstacle detection assembly 600 includes a down-going obstacle trigger switch 610 and a mounting bracket 611. The down-going obstacle trigger switch 610 is connected to the mounting bracket 611 through two sets of connection assemblies formed by hexagon socket flat round head screws, flat washers 503 and hexagon nuts. The down-going obstacle detection assembly 600 is fixed as a whole to the inner side of the bottom frame 112, and the trigger head of the down-going obstacle trigger switch 610 passes through the through hole set on the bottom frame 112 and protrudes outside the bottom frame 112, and the trigger direction is from bottom to top.

[0075] The stop plate 602 has two stop plates, a left stop plate and a right stop plate. One end of the sensing rod 601 is fixedly connected to the left stop plate by screws, and the other end is fixedly connected to the right stop plate by screws. Fig.18 and Fig.19 As shown, two lower contour detection brackets 604 are fixedly installed below the bottom frame 112. Fig.19 and Fig. 22 As shown, a connection hole is provided on the lower contour detection bracket 604, and a steel sleeve 605 is inserted into the connection hole. Bolts or other structures as connecting members 607 pass through the steel sleeve 605 to rotatably connect the two stop plates 602 and the two lower contour detection brackets 604 in a one-to-one correspondence. Specifically, the lower contour detection bracket 604 is L-shaped, and its horizontal plate is attached to the bottom of the bottom frame 112 and fixedly connected with bolts, and its vertical plate is provided with a connection hole. The stop plate 602 includes a first plate body and a second plate body connected vertically, the first plate body is attached to the vertical plate of the lower contour detection bracket 604, and is connected through a steel sleeve 605 and a connecting member 607 inserted in the steel sleeve 605; the second plate body is fixedly connected to the sensing rod 601. The stop surface 603 is located on the side of the first plate body facing the bottom frame 112.

[0076] In order to facilitate the triggering of the downhill obstacle trigger switch 610, a trigger plate 606 is fixedly mounted on the sensing rod 601. Specifically, Fig.19 and Fig.21 As shown, the trigger plate 606 is U-shaped, and the sensing rod 601 is sandwiched between two vertical plates oppositely disposed on the trigger plate 606. As the sensing rod 601 rotates, the trigger plate 606 can contact the trigger head of the down-going obstacle trigger switch 610.

[0077] like Fig.23 As shown in FIG. 1 , when the stop surface 603 is in contact with the bottom frame 112 and cannot rotate, the plane where the sensing rod 601 is located is at an acute angle to the horizontal plane. For example, the plane where the sensing rod 601 is located is set at an angle of 15° to the horizontal plane. When the sensing rod 601 encounters an obstacle, it drives the stop plate 602 to rotate relative to the lower contour detection bracket 604, as shown in FIG. Fig.24 As shown, the sensing rod 601 rotates upward to a horizontal position, driving the trigger plate 606 to press the trigger head of the downward obstacle trigger switch 610 to generate a trigger signal. The controller 700 confirms that there is an obstacle below the car 100 according to the trigger signal, and realizes obstacle detection in the downward direction.

[0078] like Fig.25 As shown, the anti-climbing device also includes a load detection component 800 , which is used to detect the load amount of the anti-climbing device. The load detection component 800 is communicatively connected with the controller 700 .

[0079] The load detection component 800 is installed on the equipment board 111 of the car 100 and has the function of detecting the load of the anti-climbing device. The controller 700 confirms the current load condition of the car 100 according to the detection value of the load detection component 800 to avoid overloading of the car 100 and improve safety.

[0080] In a specific embodiment, if Fig.26 and Fig. 27 As shown, the load detection assembly 800 includes a fixed block 801, a moving block 802 and an S-type weighing sensor 803. The fixed block 801 is fixed to the car 100, the moving block 802 is used to connect with the traction rope 900, the fixed block 801 and the moving block 802 are both connected to the S-type weighing sensor 803, and the controller 700 is in communication connection with the S-type weighing sensor 803.

[0081] Reference Fig.26 and Fig. 27 , the fixed block 801 is provided with a mounting hole, and the bolt passes through the mounting hole to install the fixed block 801 on the equipment plate 111. A first through hole is provided in the middle of the fixed block 801, and the hole axis of the first through hole is perpendicular to the hole axis of the mounting hole. The fastener 804 passes through the first through hole to fasten the fixed block 801 and the S-type weighing sensor 803. Optionally, the fastener 804 is an M12x25 hexagonal bolt; a spring washer is sleeved on the fastener 804. The moving block 802 is U-shaped, and the traction rope 900 is suspended in the middle. The moving block 802 is fastened to the S-type weighing sensor 803 through the fixing member 805. Optionally, the fixing member 805 is an M12x25 hexagonal countersunk screw. Therefore, the fixed block 801 and the movable block 802 are connected through the S-type weighing sensor 803, so that the load and the gravity of the car 100 are converted into the pressure of the fixed block 801 and the movable block 802 on the S-type weighing sensor 803. The S-type weighing sensor 803 deforms and outputs an analog electrical signal. The controller 700 can obtain the load capacity of the anti-climber device based on the analog electrical signal.

[0082] like Fig.26 and Fig. 27 As shown, a second through hole is provided on the fixed block 801, and the hole axis of the second through hole is consistent with the extension direction of the traction rope 900. The safety bolt 806 passes through the second through hole and is fastened to the moving block 802. Among them, the safety bolt 806 includes a rod body and an end cap arranged at one end of the rod body, and the end of the rod body away from the end cap is fixedly connected to the moving block 802. The rod body can move along the axial direction of the second through hole in the second through hole; the outer diameter of the end cap is larger than the aperture of the second through hole, and there is a gap between the end cap and the end face of the fixed block 801 away from the moving block 802. When the car 100 suddenly falls rapidly, the moving block 802 quickly moves away from the fixed block 801, and the end cap of the mounting bolt abuts against the fixed block 801 to avoid damage to the S-type weighing sensor 803, which plays a safety protection role and does not affect the weighing weight function of the S-type weighing sensor 803.

[0083] Specifically, there are two second through holes, which are point-symmetrically arranged on both sides of the first through hole. Optionally, the mounting bolt is an M8x30 shoulder bolt, and there is a gap between the screw head of the shoulder bolt and the end face of the fixed block 801 away from the moving block 802. For example, the gap is 2.6 mm.

[0084] The anti-climbing device provided in the embodiment of the present invention has a fixed block 801 disposed on the car 100, a moving block 802 connected to the traction rope 900, and both the fixed block 801 and the moving block 802 are connected to the S-type weighing sensor 803. Thus, the detection point of the load detection is set at the connection point between the car 100 and the traction rope 900, and the anti-climbing device as a whole can be weighed. In addition, when the operator exerts force on his hands to perform aerial work, the detection value of the S-type weighing sensor 803 will not change because the traction rope 900 does not move during the operation. The anti-climbing device provided in the embodiment of the present invention can detect any object carried by the car 100, thereby avoiding the situation that the traditional anti-climbing device can only detect objects placed on the pedal, and the situation that the detection load changes due to the operator's hand force.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
