Description

Technical Field

[0001] This invention belongs to the technical field of endless rope continuous tractor vehicles, specifically relating to an auxiliary tail car of an endless rope continuous tractor vehicle and its rope locking device. Background Technology

[0002] Endless rope continuous traction vehicles are important auxiliary transportation equipment in coal mines that operate on existing ordinary track systems. However, when the roadway where the equipment is installed has ups and downs, a single traction vehicle cannot operate well. When going downhill, the traction vehicle pulls the goods down, and when going uphill, the traction vehicle pushes the goods up, which can easily cause the vehicle to derail.

[0003] The current solution involves adding an auxiliary tail car at the end of the train to lock the steel cable, thus ensuring that the train's position remains unchanged during ups and downs, resolving the problem of derailment caused by collisions between vehicles. Since the cargo is located between the tractor and the auxiliary tail car, the steel cable of the auxiliary tail car must be loosened before loading and unloading, and the auxiliary tail car must be pushed into the yard via a loading ramp.

[0004] In certain application scenarios, this solution has a problem: because the bottom of the locking rope assembly runs below the top surface of the track, when it reaches the derailment track, such as when the straight track enters the derailment track, the locking rope part at the bottom of the auxiliary tail car will collide with the switch track section in the middle of the depot while running on the track, thus preventing the auxiliary tail car from being pushed into the depot and causing inconvenience in use.

[0005] Some existing practices involve creating clearance grooves on the turnout tracks in the middle of the depot. However, in some tunnels with many derailment tracks, many tracks need to be grooved, resulting in high processing costs. Moreover, grooving the tracks affects their structural strength and can easily lead to safety hazards. Summary of the Invention

[0006] The purpose of this invention is to provide an auxiliary tail car and its locking device for an endless rope continuous traction vehicle, which solves the problem of obstacles in the current endless rope continuous traction vehicle when the auxiliary tail car passes through the lane switch.

[0007] The technical solution provided by this invention is to provide a rope locking device for locking the auxiliary tail traction wire rope of an endless rope continuous traction vehicle, comprising:

[0008] A rope locking assembly includes a rope locking support, a rope locking cylinder fixedly installed on the top of the rope locking support, a rope clamping plate connected to a rod extending downward from the rope locking cylinder, and a rope clamping seat fixed at the bottom of the rope locking support for cooperating with the rope clamping plate.

The elastic member includes at least two members, which are disposed in the space between the locking rope support and the fixed box. The elastic member is used to push the locking rope assembly out of the fixed box by a set height when the locking member is released.

[0014] In one possible embodiment, a handle that rotates about the axis of the rotating shaft is provided on the rotating shaft or the cam.

[0015] In one possible embodiment, the locking component includes at least two locking brackets fixed to both sides of the top of the fixed box. The locking brackets are provided with screw holes, and a first screw is fitted in the screw holes. A first turntable is fixed to the top of the first screw, and a pressure plate is fixed to the bottom of the first screw.

[0016] In one possible embodiment, the locking member includes at least two fixed brackets fixedly disposed on both sides of the fixed box and a first lifting hydraulic cylinder or a first lifting air cylinder mounted on the fixed brackets. The rod end of the first lifting hydraulic cylinder or the first lifting air cylinder is fixed with a pressure plate, which can contact the top surface of the locking rope support.

[0017] In one possible embodiment, the adjustment mechanism includes an arched bracket fixed to the top of the fixed box, a threaded sleeve disposed in the middle of the arched bracket, and a second screw that cooperates with the threaded sleeve. The lower end of the second screw is fixedly connected to the cylinder body of the locking rope cylinder, and a second turntable is fixedly disposed at the upper end of the second screw.

[0018] In one possible embodiment, the adjustment mechanism includes an arched bracket fixed to the top of the fixed box, a second lifting cylinder or a second lifting air cylinder disposed in the middle of the arched bracket, and the bottom end of the rod of the second lifting cylinder or the second lifting air cylinder being fixedly connected to the cylinder body of the locking rope cylinder.

[0019] An auxiliary tail carriage for an endless rope continuous traction vehicle includes the aforementioned rope locking device.

[0020] The rope-locking device provided by the present invention sets the rope-locking assembly in a fixed box. When the auxiliary tail car passes the turnout, the rope-locking assembly is raised a certain distance in the fixed box, so that the auxiliary tail car can travel normally on the track without the need to open a clearance groove on the track.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] In the description of this specification, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with an embodiment or example that are included in at least one embodiment or example of the present invention. In this invention, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] refer to Figure 1 The diagram shows a conventional locking mechanism with a prior art structure. The locking rope assembly includes a locking rope support 14, a locking rope cylinder 11 fixedly mounted on the top of the locking rope support 14, a rope clamping plate 13 connected to a downwardly extending rod of the locking rope cylinder 11, and a rope clamping seat 12 fixed to the bottom of the locking rope support 14 for engaging with the rope clamping plate 13. The rope clamping plate 13 has a groove for engaging the wire rope, and a corresponding groove for engaging the wire rope is also provided on the rope clamping seat 12. When the locking rope cylinder 11 retracts, the rope clamping plate 13 clamps the wire rope into the space between the grooves of the rope clamping seat 12 and the rope clamping plate 13.

[0035] According to the requirements of existing rope locking assemblies, the bottom of the rope locking assembly needs to be lower than the rail by a certain height, meaning the wire rope needs to run below the top surface of the rail, that is, the bottom of the rope locking device is below the rail. When the rope locking device passes through a turnout, it will interfere with the switch track. The usual practice is to make a gap in the turnout so that the rope clamping plate 13 and the rope clamping seat 12 can pass through the gap. However, some roadways require more rail sections with gaps, which increases manufacturing costs and can easily lead to a decrease in rail strength. Therefore, this embodiment provides a rope locking device, including the following embodiments.

[0036] To solve the above problems, refer to Figures 2-4 This embodiment provides a locking device for locking the auxiliary tail traction wire rope of an endless rope continuous traction vehicle. It includes two parts: a rope locking assembly 1 and a fixing box 2.

[0040] refer to Figure 2 and Figure 4 Optionally, the locking element includes two lugs 4 fixed to both sides of the top of the fixed box 2 and a cam 5 mounted on the lugs 4 via a rotating shaft. When rotating, the cam 5 abuts against the top of the rope support 14. During rotation, the cam 5 presses down on the rope support 14, and the elastic element below pushes up, thereby locking the rope support 14 inside the fixed box 2. The elastic element includes at least two, and in this embodiment, six are arranged symmetrically on both sides. The elastic element is located in the space between the rope support 14 and the fixed box 2. The elastic element is used to push the rope assembly out of the fixed box 2 by a set height when the locking element is released, thereby avoiding the track.

[0041] Optionally, the elastic element here can be a compression spring 3. To ensure the compression amount of the compression spring 3, multiple spring mounting holes are opened on the top of the rope support 14, and a mounting plate is set inside the rope support 14. One end of the compression spring 3 is fixed to the mounting plate, and the other end is mounted on the bottom plate of the fixed box.

[0042] refer to Figure 4 Optionally, a handle that rotates around the axis of the rotating shaft or cam is provided on the rotating shaft, and the locking rope support 14 is locked by rotating the handle.

[0043] refer to Figure 6In some other possible embodiments, the locking mechanism includes two locking brackets 8 fixed to both sides of the top of the fixed box 2. Each locking bracket 8 has a screw hole, in which a first screw 9 is fitted. A first turntable is fixed to the top of the first screw 9, and a pressure plate is fixed to the bottom of the first screw 9. Rotating the first turntable moves the first screw 9 up and down, while the pressure plate presses down on the locking rope support 14.

[0044] refer to Figure 7 In some possible embodiments, the locking component includes two fixed brackets 81 fixedly disposed on both sides of the top of the fixed box 2 and a first lifting cylinder 91 mounted on the fixed brackets 81. The rod end of the first lifting cylinder 91 is provided with a pressure plate, which can contact the top surface of the locking rope support 14, thereby pressing down on the locking rope support 14.

[0045] Optionally, the first lifting cylinder 91 described above can also be replaced with a lifting cylinder or other lifting mechanism.

[0048] Optionally, the second lifting cylinder 6 mentioned above can also be replaced by a lifting cylinder or other lifting mechanism.

[0049] This invention also provides an auxiliary tail car for a continuous tractor with an endless rope, which employs the aforementioned locking device. Since the cargo is located between the tractor and the auxiliary tail car, during loading and unloading, the steel cable of the auxiliary tail car is first loosened. Then, the locking component is moved upwards a certain distance via an adjusting mechanism to allow it to pass through the switch. The auxiliary tail car is then pushed into the yard via the switch's bypass lane. When loading and unloading are not required, the rope locking assembly can be locked in a fixed box via the adjusting mechanism, making operation simple and convenient.
