Description

Technical Field

[0001] The utility model relates to the technical field of transportation safety, in particular to an anti-slip device for coal transportation. Background Art

[0002] Coal occupies a particularly important position, and safe transportation is an extremely important part of the coal production process and should be taken seriously.

[0003] However, in the prior art, most coal transport vehicles are not equipped with anti-slip devices. When the coal transport vehicle needs to park and wait or the staff needs to rest during transportation on a slope, the coal transport vehicle may slide along the slope, posing certain safety hazards. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical solution adopted by the utility model to solve the technical problems is: a device for preventing a coal transporter from slipping, comprising: a support mechanism, the support mechanism being used to support a coal transporter, the support mechanism being provided with two; a slide bar, the slide bar being used to adjust the distance between the support mechanisms, the outer wall of the slide bar being slidably connected to the inner wall of the support mechanism; a buffer fixing mechanism, the buffer fixing mechanism being used to fix the support mechanism, the outer wall of the buffer fixing mechanism being movably connected to the outer wall of the support mechanism; the support mechanism comprising a base, the outer wall of the base being rotatably connected to an arc plate, the outer wall of the top of the arc plate being fixedly connected to a rubber block, the rubber blocks being evenly arranged on the outer wall of the top of the arc plate, and the bottom of the base being fixedly connected to a gripping block.

[0005] Preferably, the outer wall of the slide rod is slidably connected to the inner wall of the base through a positioning bolt, and the outer wall of the positioning bolt is threadedly connected to the inner wall of the base. During adjustment, the positioning bolt is screwed outward until the supporting mechanism can slide along the slide rod. According to the required distance between the two wheels of the coal transport vehicle, the distance between the two supporting mechanisms is adjusted along the slide rod. After confirming the distance, the positioning bolt is screwed in until the top of the positioning bolt contacts the outer wall of the slide rod, and the spacing adjustment step is completed.

[0006] Preferably, the buffer fixing mechanism includes a casing, an inner wall of the casing is fixedly connected to a return spring, an outer wall of the return spring away from the arc plate is fixedly connected to a moving block, an outer wall of the moving block away from the return spring is fixedly connected to a hydraulic cylinder, the inner wall of the hydraulic cylinder is fixedly connected to a pressure relief cylinder via a hydraulic pipe, the inner wall of the pressure relief cylinder is slidably connected to a ground nail, the inner wall of the bottom of the casing is fixedly connected to a guide rail, and the inner wall of the top of the moving block is rotatably connected to a connecting rod.

[0007] Preferably, the side wall of the moving block is slidably connected to the outer wall of the guide rail, the outer wall of the bottom of the moving block is slidably connected to the inner wall of the bottom of the casing, the outer wall of the hydraulic cylinder is fixedly connected to the inner wall of the casing, the outer wall of the pressure relief cylinder is fixedly connected to the inner wall of the casing, and the outer wall of the return spring does not contact the inner wall of the casing. In the process of the arc plate being compressed and continuously rotating, the connecting rod connected thereto will push the moving block to move along the guide rail in the direction away from the arc plate, and the return spring connected to the moving block will be continuously stretched. The moving block will push the hydraulic cylinder while moving, and the hydraulic oil inside the hydraulic cylinder will enter the pressure relief cylinder connected thereto. When the upper chamber of the pressure relief cylinder continues to increase, the ground nails will continue to move downward and be inserted into the ground, thereby completing the fixation of the anti-skid device.

[0008] Preferably, the outer wall of the casing is fixedly connected to the outer wall of the top of the base, the outer wall of the connecting rod away from the moving block is rotatably connected to the inner wall of the bottom of the arc plate, the outer wall of the ground nail is slidably connected to the inner wall of the base, and the outer wall of the pressure relief cylinder is fixedly connected to the inner wall of the base. After use, when the wheels of the coal transport vehicle leave the outer wall of the top of the arc plate, the return spring will pull the moving block to move in the direction close to the arc plate until the return spring returns to its original length. During the movement process, the movement of the moving block will drive the hydraulic cylinder connected to it to increase the volume of its hydraulic oil chamber, and the oil chamber inside the pressure relief cylinder connected to the hydraulic cylinder will become smaller. At this time, the ground nail will continue to retract due to the pressure difference until it completely leaves the ground and retracts to the inside of the base.

[0009] The beneficial effects of the utility model are as follows:

[0010] The utility model sets a supporting mechanism and a buffer fixing mechanism to work together, so that when the coal transport vehicle is parked on the slope, the stable triangular structure of the supporting mechanism can support it, and at the same time the buffer fixing mechanism works together with the connecting spring and the hydraulic cylinder to buffer the pressure and at the same time make the ground nails inserted into the ground, and the ground nails and the gripping blocks work together to increase the contact area between the device and the ground, which greatly reduces the possibility of slipping and improves the safety of the parking state.

The buffer fixing mechanism 1 includes a casing 10, the inner wall of the casing 10 is fixedly connected with a reset spring 12, the outer wall of the reset spring 12 on the side away from the arc plate 32 is fixedly connected with a moving block 13, the outer wall of the moving block 13 on the side away from the reset spring 12 is fixedly connected with a hydraulic cylinder 14, the inner wall of the hydraulic cylinder 14 is fixedly connected with a pressure relief cylinder 15 through a hydraulic pipe, the inner wall of the pressure relief cylinder 15 is slidably connected with a ground nail 16, the inner wall of the bottom of the casing 10 is fixedly connected with a guide rail 17, and the inner wall of the top of the moving block 13 is rotatably connected with a connecting rod 11.

[0020] The side wall of the moving block 13 is slidably connected to the outer wall of the guide rail 17, the outer wall of the bottom of the moving block 13 is slidably connected to the inner wall of the bottom of the casing 10, the outer wall of the hydraulic cylinder 14 is fixedly connected to the inner wall of the casing 10, the outer wall of the pressure relief cylinder 15 is fixedly connected to the inner wall of the casing 10, the outer wall of the casing 10 is fixedly connected to the outer wall of the top of the base 31, the outer wall of the connecting rod 11 away from the moving block 13 is rotatably connected to the outer wall of the arc plate 32, the outer wall of the ground nail 16 is slidably connected to the inner wall of the base 31, and the outer wall of the pressure relief cylinder 15 is fixedly connected to the inner wall of the base 31.

[0021] Working principle:

[0022] When in use, first adjust the spacing of the support mechanism 3 of the anti-skid device, unscrew the positioning bolt 18 outward until the support mechanism 3 can slide along the slide bar 2, and adjust the distance between the two support mechanisms 3 along the slide bar 2 according to the required distance between the two wheels of the coal transport vehicle. After confirming the distance, screw in the positioning bolt 18 until the top of the positioning bolt 18 contacts the outer wall of the slide bar 2, and the spacing adjustment step is completed.

[0023] When it is necessary to fix the coal transport vehicle on the ramp, the anti-slip device is placed on the ramp so that the outer wall of the top of the curved plate 32 contacts the wheel of the coal transport vehicle, and the fixedly connected rubber block 33 on the top of the curved plate 32 contacts the wheel, which plays a certain limiting role on the wheel. The raised structures on both sides of the curved plate 32 can prevent the wheel from sliding out along the upper surface of the curved plate 32. The base 31 adopts a structure that is narrow in front and wide in the back, which can better fit the shape of the ramp. Since the front end of the base 31 is narrow, the gripping block 34 will be pressed into the ground first under the action of wheel pressure, and the friction between the ground and the gripping block 34 will fix the base 31 to prevent it from sliding relative to the ramp. Under the action of wheel pressure, the curved plate 32 will continue to rotate in the direction close to the base 31. During the continuous rotation of the curved plate 32, the connecting rod 11 connected thereto will push the moving block 13 along the guide rail 17 in the direction away from the curved plate 32. When the movable block 13 moves continuously, the return spring 12 connected thereto will be continuously stretched. At this time, the return spring 12 has a tendency to pull the movable block 13 in the direction of the arc plate 32, and the return spring 12 plays a certain buffering effect during the elongation process. The movable block 13 will push the hydraulic cylinder 14 while moving, and the hydraulic oil inside the hydraulic cylinder 14 will enter the pressure relief cylinder 15 connected thereto through the hydraulic pipe, so that the hydraulic oil chamber of the pressure relief cylinder 15 is continuously enlarged, and the two hydraulic oil chambers can also buffer the pressure transmitted by the arc plate 32 during the change process. At this time, the ground nail 16 will be squeezed by the hydraulic oil and continuously move downward and insert into the ground. When the outer wall of the arc plate 32 contacts the outer wall of the base 31, the ground nail 16 is inserted to the maximum depth. At this time, the ground nail 16 cooperates with the gripping block 34 to jointly complete the fixation of the anti-slip device, that is, to complete the fixation of the coal transport vehicle, and play a role in preventing the vehicle from slipping on the slope.

[0024] After use, when the wheels of the coal transport vehicle are no longer in contact with the curved plate 32, the return spring 12 will retract and reset, and pull the moving block 13 to move in the direction close to the curved plate 32 until the return spring 12 returns to its original length. During the movement, the moving block 13 will pull the hydraulic cylinder 14 connected thereto to allow hydraulic oil to enter the hydraulic cylinder 14, thereby increasing the volume of its hydraulic oil chamber. The hydraulic oil chamber inside the pressure relief cylinder 15 connected to the hydraulic cylinder 14 will become smaller. At this time, the ground nail 16 will continue to retract toward the inside of the base 31 due to the pressure difference until it completely leaves the ground and retracts to the inside of the base 31. After the ground nail 16 has retracted, the positioning bolt 18 is screwed out until the two supporting mechanisms 3 can slide along the outer wall of the slide rod 2, and the distance between the two supporting mechanisms 3 is adjusted to a size suitable for storage, and then the positioning bolt 18 is screwed in, and then the anti-slip device is put away for next use.
