Description

Technical Field

[0001] This utility model relates to the technical field of mining monorail cranes, and in particular to a mining monorail crane. Background Technology

[0002] A monorail crane is an auxiliary transportation device that is highly mobile, fast, has a large load capacity, and is safe and reliable. It runs on a suspended monorail system and is mainly used for installation and retraction in coal mine fully mechanized mining faces. An electric traction monorail crane is an auxiliary transportation device that is powered by a battery. It features low system operating noise, low failure rate, easy maintenance, low price, and strong climbing ability.

[0003] Rail-mounted cranes typically consist of multiple cranes. When the crane slides to the target position on the rail frame, the crane located at the rear is prone to colliding with the crane in front due to inertia, which can easily cause injury to passengers. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: when a rail-mounted monorail crane is generally set up with multiple cranes, the crane located at the rear is prone to collide with the crane in front due to inertia when the rail frame slides to the target position, which can easily cause injury to the passengers. Therefore, a mining monorail crane is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mining monorail crane includes a track, on which multiple sliding seats are horizontally slidably mounted, and a car body is fixedly mounted on each of the multiple sliding seats.

[0007] A mounting base is fixedly installed at the front end of the vehicle body. A mounting groove is provided at the upper end of the mounting base. A top block is slidably inserted into the mounting groove. A friction pad is installed at the upper end of the top block. A rectangular tube is horizontally fixedly installed on the side of the mounting base. An insertion port communicating with the inside of the rectangular tube is provided on the inner wall of the mounting groove. A movable column is horizontally slidably installed inside the rectangular tube. A right-angled trapezoidal block is fixedly installed at one end of the movable column near the mounting base. The inclined end of the right-angled trapezoidal block passes through the insertion port and abuts against the lower end of the top block.

[0008] A connecting seat is fixedly installed at the rear end of the vehicle body, and the connecting seat is connected to the movable column through a hinge assembly.

[0009] Preferably, multiple reset springs are vertically fixedly installed at the bottom of the mounting groove, and the upper ends of the multiple reset springs are fixedly connected to the lower end of the top block.

[0010] Preferably, the hinge assembly includes a first connecting rod horizontally fixedly installed at one end of the movable column, a first connecting buckle fixedly installed at one end of the first connecting rod, a second connecting rod fixedly installed on the connecting seat, and a second connecting buckle fixedly installed at one end of the second connecting rod, wherein the first connecting buckle and the second connecting buckle are sleeved on each other.

[0011] Preferably, the rectangular tube has strip-shaped holes on both the front and rear sides, and two sliders are horizontally slidably installed in each of the two strip-shaped holes, and both sliders are fixedly connected to the moving column.

[0012] Preferably, the friction pad is made of rubber and is bonded to the upper end of the top block.

[0013] Preferably, the surface of the movable column is in sliding contact with the inner wall of the rectangular tube, and a lubricant is filled between the movable column and the inner wall of the rectangular tube.

[0014] The beneficial effects of this utility model are as follows:

[0015] When multiple car bodies slide on the track, as the rear car body approaches the front car body due to inertia, it will cause the moving column to move towards the mounting base. The moving column will cause the right-angled trapezoidal block to move, and its hypotenuse will push the top block to slide upward. The friction pad at the top of the top block will contact the track and generate friction, which will have a braking effect on the front car body, thus reducing or even avoiding direct collisions between car bodies and reducing the risk of injury to passengers.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-2 A mining monorail crane includes a track 1, on which multiple sliding seats 2 are horizontally slidably installed, and a car body 3 is fixedly installed on each of the multiple sliding seats 2. The track 1 provides the operating foundation for the entire equipment. The sliding seats 2 slide in cooperation with the track 1, enabling the car body 3 to move horizontally along the track 1, thereby realizing the transportation function of multiple car bodies 3 on the track 1.

[0024] Reference Figures 3-4 A mounting base 4 is fixedly installed at the front end of the vehicle body 3. A mounting groove is provided at the upper end of the mounting base 4. A top block 5 is slidably inserted into the mounting groove. A friction pad 6 is installed on the upper end of the top block 5. A rectangular tube 7 is horizontally fixedly installed on the side of the mounting base 4. An insertion port communicating with the inside of the rectangular tube 7 is provided on the inner wall of the mounting groove. A movable column 8 is horizontally slidably installed inside the rectangular tube 7. A right-angled trapezoidal block 9 is fixedly installed at one end of the movable column 8 near the mounting base 4. The inclined end of the right-angled trapezoidal block 9 passes through the insertion port and abuts against the lower end of the top block 5.

[0025] The rectangular tube 7 provides a horizontal sliding channel for the movable column 8. The insertion port allows the right-angled trapezoidal block 9 to extend into the mounting groove and contact the top block 5. When the movable column 8 slides in the rectangular tube 7, it drives the right-angled trapezoidal block 9 to move synchronously. Since the hypotenuse of the right-angled trapezoidal block 9 abuts against the lower end of the top block 5, its movement will push the top block 5 to slide upward along the mounting groove, thereby causing the friction pad 6 to contact the track 1 and generate friction, thus achieving a braking effect and slowing down the vehicle. This reduces or even avoids direct collisions between the vehicle bodies 3 and lowers the risk of injury to passengers.

[0026] A connecting seat 10 is fixedly installed at the rear end of the vehicle body 3. The connecting seat 10 is connected to the moving column 8 through a hinge assembly. The hinge assembly connects the connecting seat 10 of the adjacent vehicle body 3 to the moving column 8, so that the movement of the front vehicle body 3 drives the movement of the rear vehicle body 3, realizing the linkage between multiple vehicle bodies 3.

[0027] Multiple return springs 11 are vertically fixed at the bottom of the mounting slot. The upper ends of the multiple return springs 11 are fixedly connected to the lower end of the top block 5. When the pushing force of the right-angled trapezoidal block 9 on the top block 5 disappears, the elastic force of the return springs 11 will pull the top block 5 to slide downward, causing the friction pad 6 to separate from the track 1, releasing the braking state, and ensuring the normal driving of the vehicle body 3.

[0028] Reference Figure 5The articulated assembly includes a first connecting rod 12 horizontally fixedly installed at one end of the movable column 8, a first connecting buckle 13 fixedly installed at one end of the first connecting rod 12, a second connecting rod 14 fixedly installed on the connecting seat 10, and a second connecting buckle 15 fixedly installed at one end of the second connecting rod 14. The first connecting buckle 13 and the second connecting buckle 15 are sleeved together. The first connecting rod 12 and the second connecting rod 14 respectively connect the first connecting buckle 13 and the second connecting buckle 15 to the movable column 8 and the connecting seat 10. The sleeved connection of the first connecting buckle 13 and the second connecting buckle 15 realizes the connection between adjacent car bodies 3, which not only ensures power transmission but also allows relative rotation between car bodies 3 to adapt to the curvature or undulation of the track 1.

[0029] The rectangular tube 7 has strip-shaped holes on both the front and rear sides. A slider 16 is horizontally slidably installed in each of the two strip-shaped holes. Both sliders 16 are fixedly connected to the moving column 8. The strip-shaped holes provide sliding space for the sliders 16. The fixed connection between the sliders 16 and the moving column 8 restricts the sliding direction of the moving column 8 in the rectangular tube 7, prevents the moving column 8 from detaching from the rectangular tube 7, and ensures its sliding stability.

[0030] The friction pad 6 is made of rubber and is bonded to the top of the top block 5. The rubber material of the friction pad 6 can increase the friction with the track 1, improve the braking effect, and at the same time have good wear resistance and cushioning, extending the service life. The bonding method makes it easy to install and replace the friction pad 6.

[0031] The surface of the movable column 8 slides in contact with the inner wall of the rectangular tube 7. Lubricant is filled between the movable column 8 and the inner wall of the rectangular tube 7. The sliding contact between the movable column 8 and the inner wall of the rectangular tube 7 ensures the horizontal movement of the movable column 8. The lubricant can reduce the sliding friction between the two, reduce wear, avoid component jamming, and adapt to the complex environment of the mine.

[0032] In this invention, when multiple vehicle bodies 3 slide on the track 1, and the rear vehicle body 3 approaches the front vehicle body 3 due to inertia, the mounting seat 4 of the rear vehicle body 3 will move closer to the connecting seat 10 of the front vehicle body 3. During this process, the moving column 8 inside the rectangular tube 7 will move towards the mounting seat 4. The moving column 8 drives the right-angled trapezoidal block 9 to move, and its hypotenuse pushes the top block 5 to slide upward. The friction pad 6 at the top of the top block 5 contacts the track 1 and generates friction, which brakes the rear vehicle body 3 and slows it down, thereby reducing or even avoiding direct collisions between vehicle bodies 3 and reducing the risk of injury to passengers.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
