Abstract
Description
Technical Field
[0001] This utility model relates to the field of track construction safety technology, specifically to a track-based locking device. Background Technology
[0002] Aerial rail transport systems have been applied in the freight sector. When conducting aerial maintenance, safety measures are required. Conventional operation involves connecting workers to safety anchors via safety ropes, which makes it inconvenient to move along the track, especially in sloping areas. This also needs to address the issue of passive locking in case of accidental falls. A safety locking device is needed that can slide along the length of the track and lock in time in case of accidents, such as falls, to prevent sliding along the track length and potential safety hazards. Utility Model Content
[0003] The main purpose of this invention is to provide a track-based locking device that solves the problem of passive locking in the event of an accidental fall while still allowing for convenient movement.
[0004] The technical solution adopted by this utility model is: a track-based locking device, including a mounting frame, which is used to span across both sides of the track;
[0005] The multiple wheels are rotatably mounted on the mounting frame and roll against the track, supporting the vertical mounting frame.
[0006] A fixing clamp is provided on the mounting frame. The fixing clamp includes a pull rod and two clamping arms that are pulsally connected to the pull rod, and is used to clamp and fix the rod on the track when the pull rod is pulled.
[0007] The positioning wheel assembly is located on both sides of the mounting frame and rolls against the lower ends of the track to prevent the mounting frame from tilting. At least one side of the positioning wheel assembly is detachably or laterally adjustable and connected to the mounting frame.
[0008] Furthermore, one end of each of the two clamping arms is hinged to the pull rod, the middle is hinged to the mounting frame, and the other end is provided with an anti-slip block for abutting the track; the mounting frame is provided with a force-bearing steering bracket higher than the connection point of the pull rod and the safety rope.
[0009] Furthermore, the clamping arm includes a telescopic arm with one end hinged to the pull rod and a lever arm fixed at an angle to the telescopic arm; the connection between the telescopic arm and the lever arm is hinged to the mounting frame.
[0010] Furthermore, the telescopic arm includes an outer sleeve and an inner sleeve disposed inside the outer sleeve and capable of sliding along the axial direction of the outer sleeve.
[0011] Furthermore, it also includes an elastic telescopic component fitted onto the pull rod, with one end of the elastic telescopic component abutting against the mounting bracket to push the pull rod downward.
[0012] Furthermore, the pull rod is provided with a limiting block, which abuts against the mounting frame to limit the pull rod when it moves vertically.
[0013] Furthermore, the positioning wheel assembly includes a mounting frame and positioning wheels rotatably mounted on the mounting frame and rolling against the sidewall of the track.
[0014] Furthermore, the mounting crossbeam is provided with a plurality of mounting holes at intervals; the mounting frame includes an adjusting crossbeam, which is provided with a plurality of adjusting positioning holes corresponding to the plurality of mounting holes; the adjusting crossbeam and the mounting crossbeam are bolted together through corresponding and connected adjusting positioning holes and mounting holes.
[0015] Furthermore, the adjusting crossbeam is provided with multiple sets of adjusting positioning holes at horizontal intervals, and any set of adjusting positioning holes can be connected to multiple mounting holes.
[0016] Furthermore, the mounting frame includes two mounting brackets for spanning the track and a connecting plate connecting the two mounting brackets; the mounting brackets are arranged opposite each other in the longitudinal direction; the mounting brackets have an inverted U-shaped structure; the positioning wheel assembly is located at the bottom of both sides of the mounting bracket and abuts against the side wall of the track.
[0017] The beneficial effects of this utility model include: 1. The mounting frame spans the track and is supported by multiple traveling wheels, and can move along the track; in the event of an accidental fall, the pull rod of the fixed clamp, connected to the safety rope, moves vertically to drive the two clamping arms to clamp and fix it on the track, achieving passive locking; the positioning wheel assembly is located on both sides of the mounting frame and rolls against both sides of the track to prevent the mounting frame from tilting; at least one side of the positioning wheel assembly is detachable or laterally adjustable and connected to the mounting frame, making it convenient to fix the positioning wheel assembly after the mounting frame is wrapped around the track; this locking device is located on the track, has no obstruction points, can move continuously along the track, and simultaneously satisfies the passive locking on the track, making it convenient to use;
[0018] 2. The connection between the clamping arm and the mounting frame of this utility model is simple. The middle part of the clamping arm, which is hinged to the mounting frame, is used as the rotation fulcrum. When the pull rod is pulled, the anti-slip block at the other end of the clamping arm can be driven to clamp and fix it on the track, thus achieving passive locking. The force-directing bracket can change the force direction of the safety rope on the pull rod. If a person falls accidentally, the safety rope will pull the pull rod upward, thus clamping the clamping arm on the track.
[0019] 3. This clamping arm has a simple structure and low manufacturing cost. It uses a lever arm to fix an anti-slip block to clamp the side wall of the track. The telescopic arms of the two clamping arms are connected to the pull rod. Since the telescopic arms can extend and retract axially, the vertical movement of the pull rod can be realized.
[0020] 4. The telescopic arm has a very simple structure. It is composed of an outer sleeve and an inner sleeve that slides inside the outer sleeve, which facilitates sliding.
[0021] 5. Through the elastic telescopic component, the mounting bracket can be used to push the pull rod downward, so that the locking device can slide on the track. In the event of an accidental fall, the vertical movement of the pull rod will not be affected, and passive locking can still be achieved.
[0022] 6. The limit block prevents the pull rod from moving too vertically downwards and avoids the clamping arm from opening too wide and extending beyond the mounting frame, thus preventing safety hazards.
[0023] 7. The positioning wheel assembly has a simple structure. It is mounted on the mounting frame via a mounting crossbeam. The positioning wheels on the mounting crossbeam roll against the side walls of the track on both sides, which can prevent the locking device from tilting and does not affect the movement of the locking device.
[0024] 8. By adjusting the crossbar and the corresponding multiple adjustment and mounting holes on the mounting crossbar, bolted connections can be made, and the detachable connection method is simple;
[0025] 9. The adjustment positioning holes are set in groups, and any group of adjustment positioning holes can be connected to multiple mounting holes, so that the horizontal position of the mounting crossbeam can be adjusted and bolted to the adjustment crossbeam.
[0026] 10. This mounting bracket has a simple structure. Two mounting brackets are fixed together by a connecting plate to form a mounting bracket that can be used to hug the track. The positioning wheel assembly is located at the bottom of both sides of the mounting bracket to support the track and prevent tilting. The connecting plate can also be used to install fixing clamps, traveling wheels and tie rods, which facilitates production.
[0027] This utility model has a simple structure and is convenient and practical. The mounting frame is straddling the track and supported by multiple traveling wheels. It can move continuously along the track. In the event of an accidental fall, the pull rod connected to the safety rope moves vertically, causing the two clamping arms to clamp and fix it on the track, achieving passive locking. The positioning wheel assembly is located on both sides of the mounting frame and rolls against both sides of the track to prevent the mounting frame from tilting. This solves the problem of not being able to meet the requirements of convenient movement while being passively locked in the event of an accidental fall. Attached Figure Description

[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0037] This utility model relates to a track-based locking device, which can be slidably installed on a track 5 to provide a safe attachment point for workers. The mounting frame 1 spans the track 5 and is supported by multiple traveling wheels 2, allowing continuous movement along the track 5. In the event of an accidental fall, the pull rod 32 connected to the safety rope moves vertically, causing two clamping arms 31 to clamp and fix the device onto the track 5, achieving passive locking. Positioning wheel assemblies 4 are located on both sides of the mounting frame 1 and roll against both sides of the track 5, preventing the mounting frame 1 from tilting. This device solves the problem of not being able to provide convenient movement while simultaneously providing passive locking in case of an accidental fall. It has a simple structure, is easy to operate and use, and has significant potential for widespread application.
[0038] A track-based locking device, such as Figure 1-4 As shown, the system includes a mounting frame 1, traveling wheels 2, fixing clamps 3, and positioning wheel assemblies 4. The mounting frame 1 is used to laterally span across both sides of the track 5. The mounting frame 1 includes an inverted U-shaped structure that can fit into the track 5. Multiple traveling wheels 2 are rotatably mounted on the mounting frame 1 and roll against the track 5 to vertically support the mounting frame 1. Preferably, two traveling wheels 2 are located on the front and rear sides of the mounting frame 1. The fixing clamp 3 is mounted on the mounting frame 1 and includes a pull rod 32 and two clamping arms 31 that are pulsively connected to the pull rod 32, for clamping and fixing on the track 5 when the pull rod 32 is pulled. The positioning wheel assemblies 4 are fixed on both sides of the mounting frame 1 and roll against the lower ends of the track 5 (the support pillars at the bottom of the track 5) to prevent the mounting frame 1 from tilting. At least one side of the positioning wheel assembly 4 is detachably or laterally adjustable and connected to the mounting frame 1. Since the positioning wheel assembly 4 rolls against the track 5 on both sides of the mounting frame 1, and the upper end of the track 5 has a large lateral width, at least one side of the positioning wheel assembly 4 can be detached and / or laterally adjustable connected to the mounting frame 1, so that the mounting frame 1 can be installed on the track 5 before the positioning wheel assembly 4 is installed or adjusted to roll against the side wall of the track 5 to laterally support the mounting frame 1.
[0039] In one embodiment, the connection method between the fixing clip 3 and the mounting bracket 1 is shown, such as... Figure 1 As shown, one end of each of the two clamping arms 31 is hinged to the pull rod 32, and the middle is hinged to the mounting frame 1 as a rotation fulcrum. The other end is provided with an anti-slip block 33 for abutting against the track 5. The anti-slip block 33 can adapt to fit the side of the track 5, and the side of the anti-slip block 33 near the track 5 is provided with anti-slip texture. The mounting frame 1 is hinged to the middle of the clamping arm 31 through the clamping arm 31 mounting bracket 11. The clamping arm 31 mounting bracket 11 can be a vertically arranged strip structure. The mounting frame 1 is provided with a force-bearing steering bracket 13. The steering force-bearing point of the force-bearing steering bracket 13 is higher than the connection point of the pull rod 32 used to connect the safety rope. Specifically, the pull rod 32 has a rope hole for installing the safety rope, and the force-bearing steering bracket 13 has a steering force point higher than the connection point between the pull rod 32 and the safety rope (i.e., the rope hole). The steering force point can be a steering hole passing through the force-bearing steering bracket 13. Preferably, the force-bearing steering bracket 13 has a steering pulley located in the steering hole for rolling and receiving the safety rope; the outer circumferential surface of the steering pulley has a curved surface that fits the safety rope. The fixing clamp 3 can be a clamp that controls the clamping arm 31 via the pull rod 32, and is not limited to the structure exemplified in this utility model. In use, one end of the safety rope is connected to the pull rod 32 (rope hole), and the other end passes through the steering hole and is connected to the worker. When the worker falls accidentally, the safety rope is pulled through the force-bearing steering bracket 13 to change the traction direction of the traction rope on the pull rod 32, so that the traction rope pulls the pull rod 32 upward, thereby tightening the clamping arm 31 to clamp the lower side wall of the track 5 and fix it on the track 5.
[0040] It is worth noting that when the fixed clamp 3 adopts the structure of clamping arm 31 clamping the track 5 when the pull rod 32 is moved down, the force-bearing bogie 13 is not used. The pull rod 32 is directly connected to the safety rope. When the worker falls, the safety rope is pulled tight, which directly causes the pull rod 32 to move down, so that the clamping arm 31 clamps and locks it on the track 5.
[0041] In a further embodiment, the structure of the clamping arm 31 is described in detail, such as... Figure 1 As shown, the clamping arm 31 includes a telescopic arm 311 hinged at one end to the pull rod 32 and a lever arm 312 fixed at an angle to the telescopic arm 311; the connection between the telescopic arm 311 and the lever arm 312 is hinged to the mounting frame 1 as a rotation fulcrum; the end of the lever arm 312 away from the telescopic arm 311 is provided with an anti-slip block 33; the end of the telescopic arm 311 away from the lever arm 312 is hinged to the pull rod 32; the telescopic arm 311 can extend and retract along its axial direction, allowing the pull rod 32 to still move vertically even when both clamping arms 31 are hinged to the mounting frame 1. When the pull rod 32 moves upward, the telescopic arms 311 extend along their axial direction and drive the lever arm 312 to rotate along the rotation fulcrum, causing the anti-slip block 33 to clamp the side wall of the track 5.
[0042] Based on the clamping arm 31, including the telescopic arm 311, such as Figure 1 As shown, one implementation of the telescopic arm 311 is illustrated. The telescopic arm 311 includes an outer sleeve and an inner sleeve disposed within the outer sleeve and slidable along the axial direction of the outer sleeve. The structure of the telescopic arm 311 is very simple; the outer sleeve and the inner sleeve slidably fitted within the outer sleeve combine to form the telescopic arm 311, facilitating sliding. The structure of the telescopic arm 311 is not limited to the structure shown in this embodiment; other structures capable of telescopic movement are also possible.
[0043] In one embodiment, such as Figure 1-2 As shown, this locking device also includes an elastic telescopic member 6, which is sleeved on the pull rod 32. One end of the elastic telescopic member 6 abuts against the mounting bracket 1 to push the pull rod 32 downward. Preferably, the elastic telescopic member 6 is a spring. The top of the spring abuts against the connecting plate 12 of the mounting bracket 1 to push the pull rod 32 downward, so that the two clamping arms 31 of the hinged pull rod 32 are in an open state, that is, in a state where the fixed track 5 is not clamped. In an optional embodiment, the lower end of the pull rod 32 is provided with a limiting protrusion. The two ends of the spring abut against the mounting bracket 1 and the limiting protrusion respectively, so that the fixing clamp 3 is in an open state. The clamping arms 31 on both sides can also be hinged to the limiting protrusion.
[0044] In a preferred embodiment, such as Figure 2As shown, the pull rod 32 is provided with a limiting block 321. When the pull rod 32 moves vertically, the limiting block 321 abuts against the mounting frame 1 to limit the pull rod 32. When used in conjunction with the elastic telescopic component 6 (spring), the elastic telescopic component 6 abuts against the mounting frame 1 to generate a downward pushing force on the pull rod 32. The bottom of the limiting block 321 abuts against the mounting frame 1 to limit the vertical downward movement of the pull rod 32, which can prevent the pull rod 32 from moving too far down, causing the clamping arm 31 to open too wide and extend beyond the mounting frame 1, thus avoiding safety hazards.
[0045] In some embodiments, such as Figure 1-2 As shown, a specific embodiment of the positioning wheel assembly 4 is illustrated. The positioning wheel assembly 4 includes a mounting frame 41 and positioning wheels 42 that are rotatably mounted on the mounting frame 41 and roll against the side wall of the track 5. The positioning wheel assembly 4 is located on both sides of the mounting frame 1 and on both sides of the track 5. By having the positioning wheels 42 on both sides roll against the track 5, the mounting frame 1 is horizontally supported, which can prevent the mounting frame 1 from tilting and does not affect the movement of the locking device on the track 5.
[0046] Based on the positioning wheel assembly 4, which includes the mounting frame 41 and the positioning wheel 42, such as Figure 1 As shown, the mounting crossbeam 41 has multiple mounting holes spaced apart; the mounting frame 1 includes an adjusting crossbeam 14, which has multiple adjusting positioning holes corresponding to the mounting holes; the adjusting crossbeam 14 and the mounting crossbeam 41 are bolted together through corresponding and connected adjusting positioning holes and mounting holes. Both the adjusting crossbeam 14 and the mounting crossbeam 41 can be plate-shaped, rod-shaped, or tubular structures, etc. Through the multiple adjusting positioning holes and mounting holes on the adjusting crossbeam 14 and the mounting crossbeam 41, bolts can be passed through for bolted connection, realizing a detachable connection.
[0047] In one embodiment, such as Figure 1 As shown, one side positioning wheel assembly 4 is fixed on the mounting frame 1, and the other side positioning wheel assembly 4 is detachably mounted on the mounting frame 1 by bolts. Both sides of the positioning wheel assembly 4 roll against the side wall of the track 5 to support the mounting frame 1 laterally, so as to prevent the mounting frame 1 from tilting to the side.
[0048] In another embodiment, the positioning wheel assemblies 4 on both sides can be detachably connected to the mounting frame 1. When the mounting frame 1 is mounted across the track 5, the positioning wheel assemblies 4 are detachably mounted on the mounting frame 1 to avoid tilting.
[0049] In one embodiment, the positioning wheel assemblies 4 on both sides are laterally adjustable and are mounted on both sides of the mounting frame 1 to roll against the side wall of the track 5 to avoid tilting.
[0050] Based on the fact that the mounting frame 41 is provided with multiple mounting holes at intervals, such as Figure 1As shown, multiple adjustment and positioning holes are divided into multiple groups, and these groups of adjustment and positioning holes are spaced apart on the adjustment crossbeam 14. Any group of adjustment and positioning holes can be connected to multiple mounting holes. This allows the mounting crossbeam 41 to be bolted to the adjustment crossbeam 14 in an adjustable position in the lateral direction. The lateral adjustment method is simple, the installation is reliable, and it is convenient for production and use.
[0051] In one embodiment, such as Figure 1-3 As shown, mounting frame 1 is illustrated. Mounting frame 1 includes a connecting plate 12 and mounting brackets 11 fixed at both ends of the connecting plate 12 for spanning the track 5. The two mounting brackets 11 are arranged opposite each other in the longitudinal direction (the length direction of the track 5). The mounting brackets 11 have an inverted U-shaped structure and can hug the track 5. The bottom of the U-shaped top of the mounting bracket 11 is fixed to the mounting plate. Positioning wheel assemblies 4 are located on both sides of the bottom of the mounting bracket 11 and roll against the side wall of the track 5. The sides and / or bottom surfaces of the two mounting brackets 11 can be connected by reinforcing plates or reinforcing ribs to improve the stability of mounting frame 1.
[0052] In actual use, the positioning wheel assembly 4 on one side is fixed to the bottom end of the mounting bracket 11 on one side, and the positioning wheel assembly 4 on the other side is detachably connected to the bottom end of the mounting bracket 11 on the other side through the adjustable horizontal plate and the mounting horizontal plate. The positioning wheels 42 of the two positioning wheel assemblies 4 roll and abut against the two sides of the track 5 at the same height. The mounting bracket 1 is fitted into the track 5 so that the traveling wheel 2 abuts against the support track 5. Then, the positioning wheel assembly 4 is bolted to the other side of the mounting bracket 11 so that the two positioning wheels 42 roll and abut against the track 5. The worker's safety rope passes through the turning hole of the force-bearing turning bracket 13 and connects to the rope hole at the upper end of the pull rod 32. In the initial state, this locking device is installed on the track 5 and is in a sliding state. In the event of an accidental fall, the safety rope at the end closest to the worker is pulled downward and tightened. After turning through the force-bearing turning bracket 13 (turning pulley), it pulls the pull rod 32 upward and moves it upward. The telescopic arm 311 extends and rotates along the pivot point, causing the lower lever arm 312 to clamp the track 5, thus achieving passive locking on the track 5. It can be used on empty tracks in slope areas and is easy to use.
[0053] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
