[0061] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0062] The following combines Figures 1 - 27 to describe the non-climbing device of the present utility model.

[0063] The present utility model provides a non-climbing device, as Figures 1 through 27 shown, which includes a car 100, a car door 200, an upper profile plate 300, a lower profile plate 400, a first closing detection component 210, a second closing detection component 310, and a controller 700. The car door 200 is installed on one side of the car 100, and the first closing detection component 210 is used to detect the closing state of the car door 200. The upper profile plate 300 is openably and closably installed on the top of the car 100, and the second closing detection component 310 is used to detect the closing state of the upper profile plate 300. The lower profile plate 400 is openably and closably installed at the bottom of the car 100. Both the first closing detection component 210 and the second closing detection component 310 are communicatively connected to the controller 700.

[0064] The car door 200 can be slidably installed on the car 100 or hinged to the car 100, as long as it can be opened and closed to provide a passage for the operator to get on and off. The first closing detection component 210 can detect the closing state of the car door 200. Before responding to the operation instruction input by the user, the controller 700 first determines whether the current car door 200 is closed based on the detection value of the first closing detection component 210, and will only respond to the operation instruction input by the user when the car door 200 is in the closed state, avoiding the operator forgetting to close the car door 200 and improving the safety factor. It can be understood that when the controller 700 determines that the car door 200 is not closed when receiving the operation instruction of the user, it controls the alarm to send an alarm message to remind the operator.

[0065] The car 100 is the main body of the non-climbing device and has the function of protecting the operator. As Figures 1 through 7 shown, the car 100 includes a cross beam 110, a longitudinal beam 130, and an equipment board 111. The cross beam 110 and the longitudinal beam 130 are connected to enclose a car frame, and the equipment board 111 is fixed to the car frame. As Figures 6 through 8As shown, on the side of the equipment board 111 facing the inside of the car 100, there is a holding handrail 123; there are two holding handrails 123, and the two holding handrails 123 are arranged in parallel. A guard plate is installed on the car frame, and the guard plate and the equipment board 111 enclose a relatively closed car body. On the side of the equipment board 111 facing the outside of the car 100, a guide wheel assembly 730 for slidingly cooperating with the lifting guide rail is installed. As Figure 5 and Figure 6 shown, there are eight groups of the guide wheel assemblies. As Figures 5 through 7 shown, on the side of the equipment board 111 facing the inside of the car 100, there are a controller 700, a storage battery 750 and a vehicle-mounted transmitter 720. The vehicle-mounted transmitter 720 is used to realize the information interaction between the controller 700 and the ground control equipment. The storage battery 750 is electrically connected to the controller 700 and the vehicle-mounted transmitter 720 to supply power to the power-consuming components. As Figure 5 and Figure 6 shown, the car 100 is provided with an upward deceleration switch 701, an upward limit switch 702 and a control handrail 703. The upward deceleration switch 701, the upward limit switch 702 and the control handrail 703 are all connected to the controller 700. Among them, the operator controls the climbing aid to decelerate and go up when approaching the working position by operating the upward deceleration switch 701, controls the climbing aid to stop going up when reaching the upward limit position by the upward limit switch 702. The control handrail 703 is an operating rod, and the operator can input corresponding control instructions to the climbing aid through the control handrail 703.

[0066] As Figure 5 shown, in order to prevent the guide wheel assembly 730 from detaching from the lifting guide rail, the car 100 is also provided with an anti-detachment assembly 740. Optionally, the anti-detachment assembly 740 includes a wedge block, and the wedge block cooperates with the wedge-shaped lifting guide rail to prevent the lifting guide rail and the car 100 from loosening during operation. As Figure 6 shown, in order to prevent the car 100 from suddenly accelerating and falling, the equipment board 111 is provided with an anti-falling assembly 731. The anti-falling assembly 731 includes a lock block capable of locking 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 lock block locks the traction rope 900 to play a role in preventing falling.

[0067] 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 board 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 arranged on the left side of the car 100, the right guard plate 121 is arranged on the right side of the car 100, and the rear guard plate 122 is arranged on the rear side of the car 100. It should be noted that the front side, the rear side, the left side and the right side are determined based on the orientation when the operator stands inside the car 100 facing the operation console.

[0068] The upper contour 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. To prevent the upper contour plate 300 from not being closed during the operation of the car 100, a second closing detection component 310 for detecting whether the upper contour plate 300 is closed is provided. 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.

[0069] The lower contour plate 400 can be installed on the bottom frame 112 in an openable and closable manner, and a rescue passage can be formed after the lower contour plate 400 is opened. Under normal circumstances, the lower contour plate 400 is in a closed state; only in case of an accident, the lower contour plate 400 is opened from the outside of the car 100 to provide a passage for rescuing the operator inside the car 100. Refer to the appendix Figure 15 , the lower contour plate 400 is installed on the bottom frame 112 through two groups of torsion spring hinge assemblies 401. The lower contour plate 400 is locked on the bottom frame 112 through the cooperation of a plum blossom nut 402 and a rivet screw 403. After loosening the plum blossom nut 402, the lower contour plate 400 automatically turns open under the action of the torsion spring built in the torsion spring hinge, exposing the lower personnel passage.

[0070] For the climber-free device provided by the embodiment of the present utility model, the car 100 serves as the main body to provide safety protection for the operator from all around. The car door 200 installed on the car 100 can provide an access passage for the operator. The opening of the upper contour plate 300 can provide an upward passage for the operator. At the same time, the first closing detection component 210 and the second closing detection component 310 are set to monitor the closing states of the car door 200 and the upper contour plate 300, so as to prevent the car door 200 and the upper contour plate 300 from not being locked before the climber-free device starts, and improve the operation safety.

[0071] As shown Figure 9 in the figure, the car 100 has a first guide rail 201 and a second guide rail 202 arranged in parallel. The opposite sides of the car door 200 are respectively slidably mounted on the first guide rail 201 and the second guide rail 202 along the longitudinal direction. The car door 200 is provided with a first locking portion 207, and the car 100 is provided with a second locking portion 208. As shown Figure 10 in the figure, when the car door 200 is in the closed state, the first locking portion 207 cooperates with the second locking portion 208 to fix the position of the car door 200 relative to the car 100. The first closing detection assembly 210 is mounted 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 the locked state.

[0072] 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 car door 200. Compared with the car door 200 hinged to the car 100, the car door 200 slidably mounted on the car 100 can save the space occupied during opening and closing, and since both sides of the car door 200 are always connected to the car 100, it is possible to prevent the car door 200 from being opened by an external force, thereby maintaining good protection performance.

[0073] As shown Figure 10 in the figure, the first locking portion 207 is a bolt slidably mounted on the car door 200, and the second locking portion 208 is a pin hole. When the car door 200 slides along the first guide rail 201 and the second guide rail 202 to the closed position, the first locking portion 207 faces the second locking portion 208, and the bolt can be inserted into the pin hole to lock the car door 200. Optionally, the first closing detection assembly 210 is a trigger switch, which is mounted in the pin hole. After the bolt is inserted into the pin hole, the first closing detection assembly 210 generates a trigger signal. The controller 700 determines that the car door 200 is in the closed state according to this trigger signal. Correspondingly, if the first closing detection assembly 210 does not generate a trigger signal before startup, the car door 200 is in the open state.

[0074] It can be understood that the car door 200 can also be in a single-door sliding mode or a double-door sliding mode.

[0075] In a specific embodiment, as shown Figure 1 and Figure 9As shown in the figure, the car door 200 includes a first sliding door 203 and a second sliding door 204. The opposite sides of the first sliding door 203 are slidably mounted along the longitudinal direction on the first guide rail and the second guide rail respectively, and the opposite sides of the second sliding door 204 are slidably mounted along the longitudinal direction on the first guide rail and the second guide rail respectively. The first sliding door 203 and the second sliding door 204 move synchronously and in opposite directions. The structure of the first sliding door 203 and the second sliding door 204 sliding relatively and opening and closing vertically can provide a larger access passage with a smaller sliding space, reducing the setting of the sliding area.

[0076] The first locking portion 207 is located on the first sliding door 203. The first sliding door 203 and the second sliding door 204 are restricted in their upward and downward positions by a limiting structure. When the first sliding door 203 and the second sliding door 204

[0077] Specifically, the climbing aid further includes a roller 205 and a lifting rope 206. The roller 205 is rotatably mounted on the car body 100. One end of the lifting rope 206 is connected to the first sliding door 203, and the other end of the lifting rope 206 bypasses the roller 205 and is connected to the second sliding door 204.

[0078] Optionally, the lifting rope 206 is a steel wire rope, which has high strength and high safety. Refer to the attached Figure 9 , two rollers 205 are mounted on the left top cross beam 117 and arranged at intervals. 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. The lifting rope 206 is laid on the two rollers 205, one end 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 upward, the second sliding door 204 moves downward synchronously; when the first sliding door 203 moves downward, the second sliding door 204 moves upward. Under the action of the lifting 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.

[0079] As Figures 11 through 14 shown in the figure, an upper fixing plate 301 is installed on the top of the car body 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 positions 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.

[0080] Optionally, the first lock body 302 is a bolt, and the second lock body 303 is a lock catch. When the upper profile plate 300 covers the upper fixing plate 301, the first lock body 302 and the second lock body 303 face each other, and the bolt can be inserted into the lock catch to lock the upper profile plate 300. As Figure 13 shown, the upper profile plate 300 is provided with two first lock bodies 302. Correspondingly, the second lock bodies 303 are provided on both opposite sides of the upper fixing plate 301. The upper fixing plate 301 includes three sequentially connected plate bodies, and the three plate bodies are respectively connected to the left top cross beam 117, the right top cross beam 118, and the middle cross beam 119 through screws in one-to-one correspondence. As Figure 13 shown, the upper profile plate 300 is installed on the upper fixing plate 301 through a hinge, and the upper profile plate 300 can be turned up to serve as a door for personnel to pass through from above. When the upper profile plate 300 is in the closed state, the upper profile plate 300 is locked and installed on the upper fixing plate 301 through the cooperation of the first lock body 302 and the second lock body 303.

[0081] As Figure 13 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 profile plate 300 is closed, the lower surface of the upper profile plate 300 triggers the micro switch and sends out an electrical signal. The controller 700 confirms that the upper profile plate 300 is closed according to the electrical signal of the micro switch, which is a precondition for starting the climber.

[0082] The upper fixing plate 301 is liftably installed on the top of the car 100. When the climber encounters an obstacle during upward movement, the upper fixing plate 301 moves in the direction close to the top of the car 100. The climber further includes an upward obstacle detection component 500, and the upward obstacle detection component 500 is communicatively connected to the controller 700. The upward obstacle detection component 500 is used to generate a trigger signal when the upper fixing 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 fixing plate 301 can also be fixed to the top of the car 100 to seal the top of the car 100. A rotatable rod is provided outside the upper fixing plate 301, and the rod rotates to trigger the upward obstacle detection component 500 after encountering an obstacle.

[0083] The upward obstacle detection component 500 is a trigger switch. At least one of the left top cross beam 117, the right top cross beam 118, and the middle cross beam 119 is provided with a second switch bracket 510, and a trigger switch is installed on each second switch bracket 510. The trigger direction of the trigger switch is from top to bottom. As Figure 11 and Figure 12As shown, a second switch bracket 510 is provided in the middle of the left top cross beam 117 and the right top cross beam 118 respectively. The second switch bracket 510 is an L-shaped plate, one of the plate bodies is attached to the cross beam 110 and fixed to the cross beam 110 by screws or other fixing structures, and the other plate body is fixedly connected to the upward obstacle detection component 500. Specifically, as Figure 11 and Figure 12 shown, each upward obstacle detection component 500 is connected to the corresponding second switch bracket 510 through two groups of hexagon socket flat head screws, washers and hexagon nuts. After the upper fixing plate 301 encounters an obstacle, it moves downward, triggering the upward obstacle detection component 500 installed on the second switch bracket 510 to output an electrical signal. The controller 700 determines that the upper profile plate 300 encounters an obstacle based on this electrical signal.

[0084] Specifically, the climber also includes a support rod 501 and an elastic member 502 sleeved on the support rod 501. One end of the support rod 501 is inserted 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 is slidably installed on the support rod 501, and the elastic member 502 is clamped between the upper fixing plate 301 and the top of the car 100. Optionally, the elastic member 502 is a compression spring.

[0085] Referring to the appendix Figures 11 through 14 , support rods 501 are provided at the front and rear ends of the left top cross beam 117 and the right top cross beam 118 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 both provided with through holes. As Figure 14 shown, the support tube 504 is arranged between the opposite faces of the cross beam 110 for support, and flat washers 503 are provided on the upper and lower sides of the cross beam 110 respectively. The support rod 501 passes through a through hole, the support tube 504, another through hole and is locked with a lock nut 505. One of the flat washers 503 is located at the locking position of the lock nut 505, and the other flat washer 503 is located at the bottom of the elastic member 502. The upper fixing plate 301 is slidably sleeved on the support rod 501. One end of the elastic member 502 abuts against the flat washer 503, and the other end abuts against the upper fixing plate 301. In the case of no obstacle, the elastic member 502 abuts the upper fixing plate 301 against the end cap of the support rod 501. In the case of encountering an obstacle, the upper fixing plate 301 moves downward along the support rod 501, compressing the elastic member 502, triggering the upward obstacle detection component 500 located at the top of the car 100, and realizing the obstacle detection in the upward direction.

[0086] 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.

[0087] As Figure 18 and Figure 19As shown, the climbing-free device further includes an induction rod 601, a stop baffle 602, and a downward obstacle detection component 600. The induction rod 601 is fixedly connected to the stop baffle 602, and the stop baffle 602 is rotatably connected to the bottom of the car 100. As Figure 23 shown, the stop baffle 602 has a stop surface 603, and the stop surface 603 can fit with the bottom of the car 100 to make the induction rod 601 inclined relative to the bottom of the car 100. As Figure 19 and Figure 20 shown, the downward obstacle detection component 600 is used to generate a trigger signal when the induction rod 601 encounters an obstacle, and the downward obstacle detection component 600 is communicatively connected to the controller 700.

[0088] Referring to Appendix Figure 19 and Appendix Figure 20 , the downward obstacle detection component 600 is fixed to the bottom of the car 100. Specifically, it is fixed to the bottom frame 112. The downward obstacle detection component 600 includes a downward obstacle trigger switch 610 and a mounting bracket 611. The downward obstacle trigger switch 610 is connected to the mounting bracket 611 through two sets of connection components formed by socket head cap screws, flat washers 503, and hex nuts. The whole downward obstacle detection component 600 is fixed to the inner side of the bottom frame 112. The trigger head of the downward obstacle trigger switch 610 passes through the through hole provided on the bottom frame 112 and protrudes outside the bottom frame 112, and the trigger direction is from bottom to top.

[0089] There are two stop baffles, a left stop baffle and a right stop baffle. One end of the induction rod 601 is fixedly connected to the left stop baffle by screws, and the other end is fixedly connected to the right stop baffle by screws. As Figure 18 and Figure 19 shown, two lower contour detection brackets 604 are fixedly installed below the bottom frame 112. As Figure 19 and Figure 22 shown, the lower contour detection bracket 604 is provided with a connection hole, a steel sleeve 605 is inserted into the connection hole, and a bolt or other structure as a connecting piece 607 passes through the steel sleeve 605 to rotatably connect the two stop baffles 602 and the two lower contour detection brackets 604 in one-to-one correspondence. Specifically, the lower contour detection bracket 604 is L-shaped. Its horizontal plate is attached to and bolted to the bottom of the bottom frame 112, and its vertical plate is provided with a connection hole. The stop baffle 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 the steel sleeve 605 and the connecting piece 607 inserted into the steel sleeve 605; the second plate body is fixedly connected to the induction rod 601. The stop surface 603 is located on one side surface of the first plate body facing the bottom frame 112.

[0090] To facilitate triggering the downward obstacle trigger switch 610, a trigger plate 606 is fixedly installed on the induction rod 601. Specifically, asFigure 19 and Figure 21 As shown in Figure 21 , the trigger plate 606 is U-shaped, and the sensing rod 601 is clamped between two oppositely arranged vertical plates of the trigger plate 606. As the sensing rod 601 rotates, the trigger plate 606 can contact the trigger head of the downward obstacle trigger switch 610.

[0091] As Figure 23 shown in Figure 23 , when the stop surface 603 fits against the bottom frame 112 and cannot rotate, the plane where the sensing rod 601 is located forms an acute angle with the horizontal plane. For example, the plane where the sensing rod 601 is located is set at an angle of 15° with the horizontal plane. After the sensing rod 601 encounters an obstacle, it drives the stop plate 602 to rotate relative to the lower contour detection bracket 604. As Figure 24 shown in Figure 24 , the sensing rod 601 rotates upward to the horizontal position, driving the trigger plate 606 to press the trigger head of the downward obstacle trigger switch 610, generating a trigger signal. The controller 700 confirms that there is an obstacle below the car 100 based on this trigger signal, realizing the detection of obstacles in the downward direction.

[0092] As Figure 25 shown in Figure 25 , the climbing-free device further includes a load detection component 800, and the load detection component 800 is used to detect the load of the climbing-free device. The load detection component 800 is communicatively connected to the controller 700.

[0093] The load detection component 800 is installed on the equipment board 111 of the car 100 and functions to detect the load of the climbing-free device. The controller 700 confirms the current load condition of the car 100 based on the detection value of the load detection component 800, avoiding overloading of the car 100 and improving safety.

[0094] In a specific embodiment, as Figure 26 and Figure 27 shown in Figure 27 , the load detection component 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 be connected to the towing rope 900, both the fixed block 801 and the moving block 802 are connected to the S-type weighing sensor 803, and the controller 700 is communicatively connected to the S-type weighing sensor 803.

[0095] Refer to Figure 26 and Figure 27, the fixing block 801 is provided with mounting holes, and bolts pass through the mounting holes to mount the fixing block 801 on the equipment board 111. A first through hole is provided in the middle of the fixing block 801, and the axis of the first through hole is perpendicular to the axis of the mounting hole. The fastener 804 passes through the first through hole to tightly connect the fixing block 801 and the S-type weighing sensor 803. Optionally, the fastener 804 is an M12x25 hexagon 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 thereof. The moving block 802 and the S-type weighing sensor 803 are tightly connected by a fixing member 805. Optionally, the fixing member 805 is an M12x25 socket head cap screw. Thus, the fixing block 801 and the moving block 802 are connected by the S-type weighing sensor 803, so that the gravity of the load and the car 100 is converted into the pressure of the fixing block 801 and the moving block 802 on the S-type weighing sensor 803. The S-type weighing sensor 803 deforms to output an analog electrical signal, and the controller 700 can obtain the load of the non-climbing device based on this analog electrical signal.

[0096] As Figure 26 and Figure 27 shown, the fixing block 801 is provided with a second through hole, and the axis of the second through hole is consistent with the extending direction of the traction rope 900. The safety bolt 806 passes through the second through hole and is tightly connected to the moving block 802. Among them, the safety bolt 806 includes a rod body and an end cap provided at one end of the rod body. 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 fixing block 801 away from the moving block 802. When the car 100 suddenly falls rapidly, the moving block 802 quickly moves away from the fixing block 801, and the end cap of the mounting bolt abuts against the fixing block 801, avoiding damage to the S-type weighing sensor 803, playing a safety protection role and not affecting the weighing function of the S-type weighing sensor 803.

[0097] Specifically, there are two second through holes, and the two second through holes are 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 bolt head of the shoulder bolt and the end face of the fixing block 801 away from the moving block 802. For example, the gap is 2.6 mm.

[0098] The climber-free device provided by the embodiment of the present utility model has a fixed block 801 arranged on the car 100. The moving block 802 is connected to the traction rope 900. Both the fixed block 801 and the moving block 802 are connected to the S-shaped weighing sensor 803. Thus, the detection point for load detection is set at the connection point between the car 100 and the traction rope 900, enabling the overall weighing of the climber-free device. Additionally, when the operator exerts force with the hand during high-altitude operations, since the traction rope 900 does not move during the operation, the detected value of the S-shaped weighing sensor 803 will not change. For the climber-free device provided by the embodiment of the present utility model, any object carried by the car 100 can be detected, avoiding the situation where traditional climber-free devices can only detect objects placed on the pedal and the change in the detected load caused by the operator exerting force with the hand.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. However, such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
