Description

Technical Field

[0001] The utility model relates to the technical field of coal mine equipment, in particular to a coal mine car blocking device. Background Art

[0002] Coal mine underground mine cars, fixed mine cars, bottom-dumping mine cars, mining flatbed trucks, dump trucks, mining material trucks, and side-dumping mine cars are the main tools for transporting materials underground in coal mines. These vehicles need to be stopped and stabilized during the transportation and loading and unloading process of the mine. This is the most critical link in the vehicle transportation process. Due to the limitations of tunnel conditions underground in coal mines, it is very easy for vehicles to slide, and even cause vehicle amplification accidents, seriously affecting the lives and safety of workers and pedestrians. The choice of vehicle-blocking devices and methods has a great impact on the reliability of vehicle transportation.

[0003] At present, the environment of underground vehicle blocking points is ever-changing, and the methods of blocking vehicles are various, such as driving wooden wedges and point pillars, but these methods of blocking vehicles are not safe and reliable, and vehicle sliding accidents often occur, resulting in casualties and equipment damage, which brings safety hazards to operators; the existing devices for preventing vehicles from sliding underground in coal mines not only have a low safety factor, but also are time-consuming and labor-intensive to operate, with high labor intensity, low work efficiency and high labor costs for workers. For this reason, we propose a coal mine vehicle blocking device to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a coal mine car blocking device, which solves the problems raised in the above background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a coal mine car blocking device, including a mine car track, a positioning socket is clamped on the outside of the mine car track, and a set rod is welded at one end of the positioning socket, two groups of symmetrically distributed adjustment components are arranged on the outside of the set rod, and locking splints are arranged on the two groups of adjustment components, and a driven wedge is provided on the outside of the locking splint, a guide rod is movably installed on the top of the positioning socket, and a blocking wedge is fixedly connected to the end of the guide rod, a transmission arm is arranged at the bottom of the blocking wedge, and a transmission wedge cooperating with the driven wedge is arranged at one end of the transmission arm, and a compression spring is movably sleeved on the outside of the guide rod.

[0006] Preferably, the cross-section of the positioning card seat is "U"-shaped, and the internal size of the positioning card seat is compatible with the mine car track.

[0007] Preferably, the adjustment assembly includes a central sleeve, a connecting bracket, and an adjustment handle. The central sleeve is movably sleeved on the outside of the sleeve rod. The upper part of the outer side of the central sleeve is fixedly connected with the adjustment handle, and the lower part of the outer side is fixedly connected with the connecting bracket.

[0008] Preferably, one end of the connecting bracket is fixedly connected to the locking clamp, and the end of the sleeve rod is threadedly connected with a locking nut.

[0009] Preferably, a non-slip rubber pad is fixedly mounted on the inner side of the locking clamping plate, and the surface of the non-slip rubber pad is provided with non-slip grooves.

[0010] Preferably, there are two groups of transmission arms, and the two groups of transmission arms are located on the left and right sides of the bottom of the vehicle-blocking wedge block, and the transmission wedge blocks at the ends of the transmission arms are against the driven wedge blocks.

[0011] Preferably, a positioning sleeve cooperating with a guide rod is provided on the top of the positioning socket, and the cross-sectional shape of the guide rod is hexagonal.

[0012] The utility model provides a coal mine car blocking device, which has the following beneficial effects:

[0013] 1. The coal mine car blocking device is clamped on the mine car track, and the blocking wedge is pressed against the wheel, and elastic force is applied to the guide rod and the blocking wedge by compressing the spring, and pressure is applied to the locking clamping plate by the transmission arm, the transmission wedge and the driven wedge, so that the locking clamping plates on both sides can clamp the side walls of the mine car track to limit the wheel. At the same time, when the wheel has a tendency to shake and applies pressure to the blocking wedge, the blocking wedge can transfer the pressure to the locking clamping plate, thereby increasing the clamping force of the locking clamping plate on the side of the mine car track and further improving the blocking effect.

[0014] 2. The coal mine car blocking device pushes the guide rod to drive the blocking wedge to move away from the adjusting component, thereby releasing the restriction of the driving wedge on the driven wedge and the locking splint. The two sets of adjusting handles are moved inward to drive the locking splint to open to both sides, and the device can be removed. The overall disassembly and assembly are simple, reducing labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1 , 2 The utility model provides a technical solution: a coal mine car blocking device, including a mine car track 1, a positioning card seat 2 is connected to the outside of the mine car track 1, and a set rod 3 is welded at one end of the positioning card seat 2, and two groups of symmetrically distributed adjusting components 4 are arranged on the outside of the set rod 3, and locking splints 5 are arranged on the two groups of adjusting components 4, and the guide rod 10 is pushed to drive the blocking wedge block 9 to move away from the adjusting component 4, and the restriction of the transmission wedge block 13 on the driven wedge block 7 and the locking splint 5 is released. The two groups of adjusting handles 43 are pulled to move inward, and the locking splint 5 is driven to open to both sides, so that the device can be removed, and the overall disassembly and assembly are simple, and the driven wedge block 7 is opened on the outside of the locking splint 5, and the top of the positioning card seat 2 is movably installed with a guide rod 10, and the guide rod 10 is movably installed on the top of the positioning card seat 2 ... The end of the rod 10 is fixedly connected with a car-blocking wedge 9. When the wheel tends to shake and applies pressure to the car-blocking wedge 9, the car-blocking wedge 9 can transfer the pressure to the locking splint 5, thereby increasing the clamping force of the locking splint 5 on the side of the mine car track 1, and further improving the car-blocking effect. A transmission arm 12 is provided at the bottom of the car-blocking wedge 9, and a transmission wedge 13 cooperating with the driven wedge 7 is provided at one end of the transmission arm 12. A compression spring 11 is provided on the external movable sleeve of the guide rod 10, and an elastic force is applied to the guide rod 10 and the car-blocking wedge 9 through the compression spring 11, and pressure is applied to the locking splint 5 through the transmission arm 12, the transmission wedge 13 and the driven wedge 7, so that the locking splints 5 on both sides can clamp the side walls of the mine car track 1 to achieve wheel restriction.

[0023] See also Figure 2 The cross-section of the positioning card seat 2 is "U"-shaped, and the internal size of the positioning card seat 2 is adapted to the mine car track 1. The positioning card seat 2 is connected to the outside of the mine car track 1 to position the device and ensure the stability of the device after installation on the mine car track 1.

[0024] See also Figure 3 , 5The adjusting assembly 4 includes a central sleeve 41, a connecting bracket 42, and an adjusting handle 43. The central sleeve 41 is movably sleeved on the outside of the sleeve rod 3. The upper part of the outer side of the central sleeve 41 is fixedly connected with an adjusting handle 43, and the lower part of the outer side is fixedly connected with a connecting bracket 42. The guide rod 10 is pushed to drive the car blocking wedge 9 to move away from the adjusting assembly 4, and the restriction of the transmission wedge 13 on the driven wedge 7 and the locking splint 5 is released. The two sets of adjusting handles 43 are moved inward, driving the locking splint 5 to open to both sides, and the device can be removed. The overall disassembly and assembly are simple.

[0025] One end of the connecting bracket 42 is fixedly connected to the locking clamp plate 5, and the end of the set rod 3 is threadedly connected with a locking nut 8. The two groups of adjustment components 4 are restricted by the locking nut 8 to ensure the stability of the two groups of adjustment components 4 after being installed on the outside of the set rod 3, and at the same time, it is convenient to disassemble and assemble the adjustment components 4. The inner side of the locking clamp plate 5 is fixedly installed with an anti-slip rubber pad 6, and the surface of the anti-slip rubber pad 6 is provided with anti-slip grooves. By arranging the anti-slip rubber pad 6 on the inner side of the locking clamp plate 5, the friction between the device and the mine car track 1 after installation is improved, thereby improving the car-blocking effect.

[0026] See also Figure 2 , 4 There are two groups of transmission arms 12, and the two groups of transmission arms 12 are located on the left and right sides of the bottom of the car-blocking wedge block 9. By setting two groups of transmission arms 12, it is ensured that the car-blocking wedge block 9 can stably transmit the pressure to the locking clamp plate 5. The transmission wedge block 13 at the end of the transmission arm 12 is against the driven wedge block 7, and the elastic force is applied to the guide rod 10 and the car-blocking wedge block 9 through the compression spring 11, and the pressure is applied to the locking clamp plate 5 through the transmission arm 12, the transmission wedge block 13 and the driven wedge block 7, so that the locking clamp plates 5 on both sides can clamp the side walls of the mine car track 1 to achieve the restriction of the wheel.

[0027] A positioning sleeve 14 cooperating with the guide rod 10 is provided at the top of the positioning base 2. The positioning sleeve 14 is used to limit the guide rod 10 to ensure that the guide rod 10 is stably installed on the top of the positioning base 2, and at the same time, the guide rod 10 can slide stably along the axial direction. The cross-sectional shape of the guide rod 10 is hexagonal. The cross-sectional shape of the guide rod 10 is restricted so that the guide rod 10 can only move stably along the axial direction, thereby preventing the wedge block 9 from rotating axially along the guide rod 10.

[0028] In summary, when the coal mine car blocking device is in use, when the mine car needs to be blocked during loading and unloading, the device is clamped on the outside of the mine car track 1, and the blocking wedge 9 is pressed tightly against the mine car wheel, and the compression spring 11 applies elastic force to the guide rod 10 and the blocking wedge 9, so that the blocking wedge 9 always has a tendency to move toward the side close to the adjustment component 4, and the transmission arm 12, the transmission wedge 13 and the driven wedge 7 are used to apply pressure to the locking clamp 5, so that the anti-skid rubber pad 6 on the inside of the locking clamp 5 clamps the side wall of the mine car track 1, and the device is locked on the mine car track 1, so as to limit the mine car wheel and achieve the effect of blocking the car. When the mine car wheel tends to shake, the wheel applies pressure to the car-blocking wedge 9, which is transmitted through the transmission arm 12, the transmission wedge 13 and the driven wedge 7, and the pressure is transmitted to the locking clamp 5, and the pressure applied by the wheel on the car-blocking wedge 9 is converted into the clamping force of the locking clamp 5 on the mine car track 1, thereby improving the car-blocking effect. After the mine car is loaded and unloaded, the guide rod 10 is pushed to drive the car-blocking wedge 9 to move away from the adjustment component 4, and the restriction of the transmission wedge 13 on the driven wedge 7 and the locking clamp 5 is released, and the two sets of adjustment handles 43 are moved inward, driving the two sets of locking clamps 5 to open to both sides, and the device is removed.
