Description

Technical Field

[0001] This invention relates to the field of mining car technology, and more specifically to an automatic hook-and-unhook device for mining cars. Background Technology

[0002] Currently, mines typically use electric locomotives to pull mine cars to complete ore (rock) transportation tasks. During the process of hoisting into and out of the cage in the vertical shaft and after reaching the end of the line, the mine cars need to be grouped and unhooked (hooked).

[0003] Traditionally, the unhooking and unhooking of mine cars are done manually, which not only requires more manpower and wastes manpower, but also poses certain safety hazards because people have to get close to the mine car to operate it manually. Summary of the Invention

[0004] In view of the problems existing in the current automatic unhooking and hooking devices for mining cars, the present invention is proposed.

[0005] Therefore, the purpose of this invention is to provide an automatic hook-and-unhook device for mine cars, which solves the problem that in the prior art, the hook-and-unhook actions of mine cars are all done manually. This not only requires more manpower and wastes manpower, but also poses certain safety hazards because people have to approach the mine car to operate it manually.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic hook-and-unhook device for a mining car includes a front hook and a rear hook. The front hook is disposed on one side of the rear hook. A groove is formed on the side of the front hook near the rear hook. A push rod is fixedly disposed on the side of the rear hook near the front hook. One end of the push rod extends into the inner side of the groove. Cavities are formed on both sides of the groove. A stop block is slidably disposed inside the cavity. A stop rod is fixedly sleeved in the middle of the stop block. Both ends of the stop rod extend into the outer side of the cavity. A slot is formed on both sides of the push rod at a position corresponding to the stop rod. One end of the stop rod is engaged with the corresponding... The push rod has a slotted engagement mechanism. Both sides of the push rod near the front coupler have first inclined surfaces. Both stop rods have second inclined surfaces near the push rod. The first and second inclined surfaces have the same inclination angle. A through groove is formed on the side wall of the stop rod away from the push rod. A third inclined surface is formed on the side of the through groove away from the push rod. Push plates are slidably mounted on both sides of the front coupler. A fourth inclined surface is formed on the side of the push plate near the third inclined surface. The third and fourth inclined surfaces abut against each other. A transmission mechanism is provided on the outer wall of the front coupler to move the push plates on both sides.

[0007] Preferably, the transmission mechanism includes an annular electromagnet and an iron ring. The annular electromagnet is fixedly sleeved on the outer wall of the front coupler. The iron ring is disposed on the side of the annular electromagnet away from the stop bar. The iron ring is movably sleeved with the front coupler. Connecting rods are movably sleeved inside both ends of the annular electromagnet. The two ends of the connecting rods are fixedly connected to the corresponding push plate and the iron ring, respectively.

[0008] Preferably, a first spring is movably sleeved on the wall of the stop rod, one end of the first spring is fixedly connected to the side of the stop plate away from the push rod, and the other end of the spring is fixedly connected to the inner wall of the corresponding cavity.

[0009] Preferably, a second spring is movably sleeved on the wall of the connecting rod, one end of the second spring is fixedly connected to an annular electromagnet, and the other end of the second spring is fixedly connected to an iron ring.

[0010] Preferably, both the baffle and the cavity have rectangular cross-sections.

[0011] Preferably, a connecting plate is fixedly provided at the opposite ends of the front and rear couplers.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. In this invention, the rear coupler approaches the front coupler, causing the push rod to enter the groove of the front coupler. The third inclined surface presses against the corresponding fourth inclined surface, causing the stop rod to move away from the push rod. After the push rod enters the groove, the first spring pushes the stop rod to reset, causing the stop rod to insert into the slot on the side wall of the corresponding push rod, thus completing the automatic hooking action of the front and rear couplers.

[0013] 2. In this invention, by energizing a ring electromagnet, an iron ring can be magnetically attracted, causing the iron ring to move closer to the ring electromagnet. This, in turn, causes the connecting rod to push the push plate, which in turn causes the second inclined surface to push the first inclined surface. This moves the stop rod away from the push rod, thereby releasing the limit on the push rod and realizing the automatic unhooking action of the front and rear couplers. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This invention discloses an automatic hook-and-unhook device for mining cars.

[0019] Reference Figure 1-3 An automatic hook-and-unhook device for mine cars includes a front hook 1 and a rear hook 2. The front hook 1 is located on one side of the rear hook 2. Connecting plates are fixedly installed at opposite ends of both the front hook 1 and the rear hook 2 to facilitate installation of the front hook 1 and the rear hook 2 onto the corresponding mine cars. A groove is formed on the side of the front hook 1 near the rear hook 2, and a push rod 3 is fixedly installed on the side of the rear hook 2 near the front hook 1. One end of the push rod 3 extends into the inner side of the groove. Cavities are formed on both sides of the groove, and a stop block is slidably installed inside each cavity. A stop rod 4 is fixedly sleeved in the middle of the stop block. Both the stop plate 10 and the cross-section of the cavity are rectangular, preventing the stop plate 10 from rotating, thus ensuring stability. With a certain sliding motion, both ends of the stop rod 4 extend to the outside of the cavity. The two sides of the push rod 3 are provided with slots corresponding to the stop rod 4. One end of the stop rod 4 is engaged with the corresponding slot. The two sides of the push rod 3 near the front hook 1 are provided with first inclined surfaces. The two stops 4 near the push rod 3 are provided with second inclined surfaces. The first inclined surfaces and the corresponding second inclined surfaces have the same inclination angle. The side wall of the stop rod 4 away from the push rod 3 is provided with a through groove. The side of the through groove away from the push rod 3 is provided with a third inclined surface. Push plates 7 are slidably provided on both sides of the front hook 1. The side of the push plate 7 near the third inclined surface is provided with a fourth inclined surface. The third inclined surface and the corresponding fourth inclined surface abut against each other.

[0020] Reference Figure 1-3 The outer wall of the front hook 1 is provided with a transmission mechanism that drives the push plates 7 on both sides to move. The transmission mechanism includes an annular electromagnet 5 and an iron ring 6. The annular electromagnet 5 is fixedly sleeved on the outer wall of the front hook 1. The iron ring 6 is located on the side of the annular electromagnet 5 away from the stop bar 4. The iron ring 6 is movably sleeved with the front hook 1. Both ends of the annular electromagnet 5 are movably sleeved with connecting rods 9. The two ends of the connecting rods 9 are fixedly connected to the corresponding push plates 7 and iron rings 6, respectively.

[0021] Reference Figure 1-3The first spring 8 is movably sleeved on the wall of the stop rod 4. One end of the first spring 8 is fixedly connected to the side of the baffle 10 away from the push rod 3, and the other end of the spring is fixedly connected to the inner wall of the corresponding cavity, which improves the stability of the insertion of the stop rod 4 into the slot.

[0022] Reference Figure 1-3 The connecting rod 9 has a second spring 11 movably sleeved on its wall. One end of the second spring 11 is fixedly connected to the annular electromagnet 5, and the other end of the second spring 11 is fixedly connected to the iron ring 6, so that the iron ring 6 can be reset.

[0023] In this invention, during use, the rear hook 2 approaches the front hook 1, causing the push rod 3 to enter the groove of the front hook 1. The third inclined surface presses against the corresponding fourth inclined surface, causing the stop rod 4 to move away from the push rod 3. After the push rod 3 enters the groove, the first spring 8 pushes the stop rod 4 to reset, causing the stop rod 4 to insert into the slot on the side wall of the corresponding push rod 3, thus completing the automatic hooking action of the front and rear hooks. When the annular electromagnet 5 is energized, it can magnetically attract the iron ring 6, causing the iron ring 6 to move towards the side closer to the annular electromagnet 5. This causes the connecting rod 9 to push the push plate 7 to move, causing the second inclined surface to push the first inclined surface, thus moving the stop rod 4 away from the push rod 3, thereby releasing the limit on the push rod 3 and realizing the automatic unhooking action of the front hook 1 and the rear hook 2.

[0024] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
