Abstract
Description
Technical Field
[0001] This utility model belongs to the field of buffer equipment technology, specifically a vehicle-stopping buffer device at the end of a monorail suspended beam. Background Technology
[0002] In existing coal mine operations, there is generally a lack of buffer devices between the end-of-track brake and the monorail crane. When the monorail crane collides with the brake at the end of the track, the instantaneous impact force will cause serious damage to the monorail crane's body structure, suspension components, and the brake itself due to the lack of a buffer structure. This will greatly shorten the service life of the equipment and increase maintenance costs and equipment replacement frequency.
[0003] At the same time, such unbuffered hard collisions may cause equipment parts to loosen or fall off, or even cause the monorail to derail, seriously threatening the lives of underground workers and posing a major safety hazard. Utility Model Content
[0004] This invention provides a vehicle-stopping buffer device at the end of a monorail suspended beam to address the deficiencies in the prior art.
[0005] This utility model is achieved through the following technical solution:
[0006] A single-rail suspension beam end-stopping buffer device includes side plates disposed on both sides of the single-rail suspension beam. The inner side of the side plate extends into the sliding groove of the single-rail suspension beam and slides along the single-rail suspension beam. A strip-shaped groove is laterally opened on the side plate. A push rod is slidably disposed in the strip-shaped groove. The outer end of the push rod passes through a circular hole and extends laterally toward the vehicle stopper. A blocking plate is fixedly disposed on the outer end of the push rod. The blocking plate and the fixed block are fixedly connected by a spring sleeved on the push rod. When the spring is compressed to its shortest length, the inner end of the push rod is in contact with the inner wall of the end of the strip-shaped groove.
[0007] When this application is in use, when the monorail moves near the car stop, it will push the side plate to move along the direction of the monorail beam. Then, the blocking plate will first contact the car stop, and the compression spring of the blocking plate will drive the push rod to move in the opposite direction in the strip groove. The spring will deform and convert the kinetic energy generated by the collision into elastic potential energy, thereby absorbing the impact force and avoiding serious damage to the monorail's body structure, suspension components and the car stop itself caused by the instantaneous impact force. This will ensure the service life of the equipment, reduce maintenance costs and equipment replacement frequency, and protect the safety of the staff.
[0008] Preferably, the two side plates have through holes on their opposite surfaces, and a pin passes through the opposite through holes. One end of the pin is fixedly fitted with a baffle, and the other end has an external thread and is threaded to a compression nut. The pin achieves a fixed connection between the two side plates.
[0009] Preferably, the side of the strip-shaped groove is provided with a sliding groove along its length, with two sliding grooves facing each other vertically. A slider is slidably fitted inside the sliding groove, and the opposing surface of the slider extends out of the sliding groove and is fixedly connected to the push rod. The sliding groove not only ensures that the push rod moves smoothly within the strip-shaped groove, but also limits the push rod and prevents the outer end of the push rod from warping.
[0010] Preferably, the side plate has a mounting groove on the side facing the vehicle stopper. The mounting groove is connected to the strip groove and the sliding groove. A mounting plate is provided in the mounting groove. The mounting plate is fixedly connected to the side plate by bolts. The corresponding end of the spring is fixedly mounted on the mounting plate.
[0011] Preferably, the pin is coaxially fixedly connected to the inner wall of the bearing inner ring, and a rubber wheel is sleeved on the outer wall of the bearing outer ring. The rubber wheel can contact the top surface of the monorail beam. The rubber wheel can not only better suspend the pin on the monorail beam, but also reduce the friction between the pin and the monorail beam.
[0012] Preferably, the upper and lower parts of the side plate are provided with transverse through slots, and the strip slot is located between the two through slots. The through slots can reduce the weight of the side plate while meeting the requirements for normal use, thereby reducing the impact force.
[0013] The beneficial effects of this utility model are as follows: The use of this application can utilize springs, push rods, and blocking plates to avoid direct contact between the monorail and the car stopper. At the same time, by utilizing the deformation of the spring, the kinetic energy generated by the collision is converted into elastic potential energy, thereby absorbing the impact force and avoiding serious damage to the monorail's body structure, suspension components, and the car stopper itself caused by the instantaneous impact force. This ensures the service life of the equipment, reduces maintenance costs and equipment replacement frequency, and protects the safety of the staff. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0021] A single-rail suspension beam end braking buffer device, such as Figure 1-3 As shown. It includes side plates 2 set on both sides of the monorail beam 1. The inner side of the side plate 2 extends into the sliding groove 7 of the monorail beam 1 and slides along the monorail beam 1. The side plate 2 has a transverse strip groove 3. A push rod 4 is slidably arranged in the strip groove 3. The outer end of the push rod 4 passes through a round hole and extends laterally towards the vehicle stop. A blocking plate 5 is fixedly set on the outer end of the push rod 4. A rubber pad is set on the outer side of the blocking plate 5. The blocking plate 5 and the fixing block are fixedly connected by a spring 6 sleeved on the push rod 4. When the spring 6 is compressed to its shortest length, the inner end of the push rod 4 is in contact with the inner wall of the end of the strip groove.
[0022] When this application is in use, when the monorail moves to the vicinity of the car stopper, it will push the side plate 2 to move along the direction of the monorail beam 1. Then, the blocking plate 5 will first contact the car stopper, and the blocking plate 5 will compress the spring 6, causing the push rod 4 to move in the opposite direction in the strip groove 3. The spring 6 will deform, converting the kinetic energy generated by the collision into elastic potential energy, thereby absorbing the impact force and avoiding serious damage to the monorail's body structure, suspension components and the car stopper itself caused by the instantaneous impact force. This will ensure the service life of the equipment, reduce maintenance costs and equipment replacement frequency, and protect the safety of the staff.
[0023] The two side plates 2 have through holes on their opposite faces, and a pin 10 passes between the opposite through holes. One end of the pin 10 is fixedly equipped with a baffle, and the other end has an external thread and is threaded to a compression nut. The pin 10 is used to fix the two side plates 2 together. The pin 10 is coaxially fixed to the inner wall of the inner ring of the bearing, and a rubber wheel 11 is sleeved on the outer wall of the outer ring of the bearing. The rubber wheel 11 can contact the top surface of the monorail beam 1. The rubber wheel 11 can not only better suspend the pin 10 on the monorail beam 1, but also reduce the friction between the pin 10 and the monorail beam 1.
[0024] The side of the strip-shaped groove is provided with a sliding groove 7 along its length. Two sliding grooves 7 are positioned vertically opposite each other, and a slider 8 is slidably fitted inside the sliding groove 7. The opposing surfaces of the slider 8 protrude from the sliding groove 7 and are fixedly connected to the push rod 4. The sliding groove 7 not only ensures that the push rod 4 moves smoothly within the strip-shaped groove 3, but also limits the movement of the push rod 4 to prevent the outer end of the push rod 4 from warping.
[0025] The side plate 2 has an installation groove on the side facing the vehicle stopper. The installation groove is connected to the strip groove 3 and the sliding groove 7. An installation plate 9 is provided in the installation groove. The installation plate 9 is fixedly connected to the side plate 2 by bolts. The corresponding end of the spring 6 is fixedly set on the installation plate 9.
[0026] The upper and lower parts of the side plate 2 are both horizontally provided with through grooves 12, and the strip groove 3 is located between the two through grooves 12. The through grooves 12 can reduce the weight of the side plate 2 while meeting the requirements for normal use, thereby reducing the impact force.
[0027] The use of this application can utilize the spring 6, push rod 4, and stop plate 5 to prevent direct contact between the monorail and the car stopper. At the same time, the deformation of the spring 6 converts the kinetic energy generated by the collision into elastic potential energy, thereby absorbing the impact force and preventing serious damage to the monorail's body structure, suspension components, and the car stopper itself caused by the instantaneous impact force. This ensures the service life of the equipment, reduces maintenance costs and equipment replacement frequency, and protects the safety of the staff.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
