Description

Technical Field

[0001] The utility model relates to a buffering and stopping device for a sleeper demoulding roller conveyor, and belongs to the technical field of concrete product transport roller conveyors. Background Art

[0002] The sleeper, also known as the sleeper, is a type of railway accessory. Its main function is to support the rails, maintain the position of the rails, and transfer the huge pressure transmitted from the rails to the roadbed. The sleeper needs to have a certain degree of flexibility and elasticity so that it can deform appropriately to buffer the pressure when the train passes, and it also needs to return to its original shape as much as possible after the train passes. The switch sleeper is a special sleeper used on railway switches. It is mainly used at the switch traction point, and the switch electrical conversion rod can be placed in the sleeper, which is conducive to large machine maintenance operations. Compared with ordinary sleepers, switch sleepers have higher strength and stability, can withstand greater force and impact, and ensure the stability and safety of trains when traveling at high speeds and frequently switching tracks. When transporting sleepers and switch sleepers, it is usually necessary to install a stop device at the end of the transport roller to serve as a stop. In actual work, there are many types of prestressed concrete sleepers and switch sleepers, and the lengths of switch sleepers are different. Taking the switch sleeper sc330 as an example, the length of the switch sleeper ranges from 2.4m to 4.8m. If the end length of the transport roller is fixed, it can meet the parking and transportation requirements of the sleepers but not the parking and transportation requirements of the switch sleepers. This phenomenon seriously reduces the production efficiency of the enterprise and increases the production cost of the enterprise. In addition, unreasonable sleeper roller transportation can easily cause safety hazards in operations.

[0003] The existing roller buffer stop device is usually only suitable for the parking and transportation of sleepers, and cannot meet the parking and transportation of switch sleepers at the same time. In addition, the buffer stop effect on the sleepers is poor, which can easily cause damage to the sleeper ends and affect the working effect of the roller buffer stop device. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] like Figure 1-4 As shown, the utility model provides a rail sleeper demoulding roller buffer stop device, including a roller base 11, a base 10 is symmetrically provided on the top of the roller base 11, and a connecting rod 8 with the same rotatable connection is provided on the top of the two bases 10. A fixing mechanism is sleeved on the outer wall of the connecting rod 8 between the two bases 10, and a baffle 1 is provided on the top of the fixing mechanism. The same rotating mechanism is provided on one side of the baffle 1 above the two bases 10; the inner side of the fixing mechanism is detachably connected to a limiting rod 3, and the base 10 is provided with a spring mechanism on one side of the limiting rod 3, and the spring mechanism is detachably connected to the limiting rod 3.

[0027] Specifically, when the rail sleeper is blocked, the rotating mechanism contacts the rail sleeper when the rail sleeper in transportation moves to one side of the baffle 1, and supports the rail sleeper, and then one end of the rail sleeper contacts the baffle 1, and the force is transmitted to the baffle 1, so that the baffle 1 and the fixing mechanism are deflected around the connecting rod 8, the limiting rod 3 moves with the fixing mechanism, so that the spring mechanism is compressed, and then the spring mechanism returns to the original position, until the baffle 1 returns to the vertical state, thereby adjusting the position of the rail sleeper, and positioning the rail sleeper, ensuring that the end of the rail sleeper is flush, facilitating subsequent processing work, and the spring mechanism buffers the collision between the baffle 1 and the rail sleeper, and protects the end of the rail sleeper; when the turnout sleeper is worked, the limiting rod 3 can be detached from the fixing mechanism, and the baffle 1 and the fixing mechanism are rotated around the connecting rod 8, so that the baffle 1 and the fixing mechanism are located below the turnout sleeper, providing more space for the end of the turnout sleeper, and the rotating mechanism positions the turnout sleeper, avoiding the phenomenon that the end distance is not enough during transportation of the turnout sleeper, and the phenomenon that the turnout sleeper cannot be transported, thereby facilitating parking and transportation of the turnout sleeper, so that the device can be applied to parking and transportation of the rail sleeper and the turnout sleeper, and the working effect of the device is ensured; the rotating mechanism is used for limiting the baffle 1, and when the spring mechanism is in a normal state, the baffle 1 is in a vertical state and located on one side of the rotating mechanism, and the rotating mechanism limits one side of the baffle 1, so as to avoid separation of the spring mechanism and the limiting rod 3.

[0028] The baffle 1, the limiting rod 3, the spring mechanism and the fixing mechanism cooperate to buffer and stably stop the rail sleeper in transmission, which is beneficial to protect the quality of the rail sleeper and avoid damage of the end of the rail sleeper, and the positioning effect of the rail sleeper is achieved, so that the end of the rail sleeper is flush, facilitating subsequent processing work; meanwhile, the limiting rod 3 can be detached, and the positions of the fixing mechanism and the baffle 1 are adjusted, so that more space is provided for the end of the turnout sleeper when the turnout sleeper is worked, and the parking and transportation of the turnout sleeper are facilitated, so that the device can meet the parking and transportation of the rail sleeper and the turnout sleeper, and the working effect of the device is ensured.

[0029] In one embodiment, the fixing mechanism includes two fixing frames 4, the two fixing frames 4 are symmetrically sleeved on the outer walls of the connecting rod 8, the fixing frames 4 are provided with fixing columns 2 at the top, and the baffle 1 is fixedly connected with the two fixing columns 2; when the baffle 1 is pushed, the fixing columns 2 drive the fixing frames 4 to move, and the two fixing frames 4 support the baffle 1, so as to ensure the stability of the position of the baffle 1.

[0030] As Figure 2As shown, in one embodiment, a through hole 12 is provided on the outer wall of the fixing frame 4 for passing the limiting rod 3, and the fixing frame 4 can be displaced up and down relative to the through hole 12. When the limiting rod 3 needs to be disassembled, the spring mechanism can be pressed to pull the limiting rod 3 out of the through hole 12. When the limiting rod 3 needs to be reinstalled, the limiting rod 3 can be placed inside the through hole 12 and positioned above the spring mechanism. The spring mechanism can push the limiting rod 3 to contact the top of the through hole 12, thereby positioning the limiting rod 3.

[0031] In one embodiment, the spring mechanism includes a spring base 7 and a spring top seat 13, the spring base 7 is arranged at the top of the base 10, a spring 6 is provided between the spring base 7 and the spring top seat 13, the spring top seat 13 is detachably connected to the limiting rod 3, a spring pressure pad 5 is provided on the top of the spring top seat 13, the spring pressure pad 5 is detachably connected to the limiting rod 3, and the top of the spring pressure pad 5 is symmetrically provided with limit blocks 14 on both sides of the limit rod 3, and the two limit blocks 14 cooperate to limit the left and right sides of the limit rod 3.

[0032] Specifically, when the baffle 1 is offset by the force of the sleeper, the limit block 14 limits the limit rod 3, so that the limit rod 3 drives the spring pressure pad 5 and the spring top seat 13 to move downward, and the spring top seat 13 and the spring base 7 approach each other, so that the spring 6 is compressed, thereby playing a buffering role for the sleeper. The spring pressure pad 5 is used to bear the pressure, and the limit block 14 only limits the two sides of the limit rod 3. When the limit rod 3 needs to be disassembled, the limit rod 3 can be directly pulled out from the side, ensuring the convenience of the device.

[0033] In one embodiment, a connecting rod fixing frame 9 is provided on the top of the base 10, and the connecting rod 8 is rotatably connected to two of the connecting rod fixing frames 9 at the same time. The connecting rod fixing frames 9 support the connecting rod 8, thereby ensuring the stability of the structure of the device.

[0034] like Figure 3-4 As shown, an embodiment, the rotating mechanism includes a rotating roller 15 and a motor (not shown in the figure) for driving the rotating roller 15 to rotate. When the sleeper is parked and transported, the rotating roller 15 can support the sleeper to prevent the sleeper from falling off the transport roller, thereby ensuring the stability of the sleeper when in contact with the baffle 1; when working on the switch sleeper, the motor can be used to drive the rotating roller 15 to rotate, thereby assisting the switch sleeper in transporting the switch sleeper and controlling the switch sleeper to park the switch sleeper; at the same time, the rotating roller 15 blocks the baffle 1, preventing the baffle 1 from rotating toward the rotating roller 15, causing the limit rod 3 to separate from the spring pressure pad 5, thereby ensuring the stability of the device when working.

[0035] Specifically, when the present application is working on the sleepers, the sleepers are transported to the end of the roller conveyor via the roller conveyor, and pressure is applied to the fixed column 2 and the baffle 1. At the same time, the pressure is transmitted to the spring 6 through the fixed frame 4, the limit rod 3 and the spring pressure pad 5. The deformation of the spring 6 reduces the impact force of the sleeper end on the baffle 1, which can protect the sleeper end and reduce the probability of end damage. At the same time, the sleeper ends can be aligned, the sleeper position can be adjusted, the sleeper can be raised and lowered, and the sleeper falls onto the transverse transmission chain, and the sleepers are transported to the front end, in groups of four, and a special sleeper gathering machine is used to stack the sleepers layer by layer; when producing switch sleepers, the limit rod 3 is removed to provide more space for the sleeper transportation end, which facilitates the parking and transportation of switch sleepers.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
