DETAILED DESCRIPTION
[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0024] The utility model provides a kind of technical scheme of mine roadway track car blocking stopping speed regulating machine.
[0025] As shown in Figures 1-5 , including bearing box 1, the top surface of bearing box 1 is provided with a group of symmetrically distributed track connecting holes 19, by the arrangement of track connecting hole 19, it is convenient for staff to use bolt and other existing tools to install mine roadway track to the upper of bearing box 1, the present application can realize the blocking of vehicle, stopping and speed regulating operation by one device, effectively improve the applicability of device, greatly reduce the security risk of operation.
[0026] The inside of the bearing box 1 is fixedly connected with a support shaft 2, the outer surface of the support shaft 2 is rotatably connected with a vehicle stop 3, the bottom end of the vehicle stop 3 is fixedly connected with a reset counterweight box 4, the vehicle stop 3 can block the vehicle in one direction when it is upright, and the effect of stopping the vehicle is achieved, and when a vehicle in the opposite direction passes, the vehicle can contact the vehicle stop 3, at this time the vehicle stop 3 will be laid down in the bearing box 1 along the driving of the vehicle, and will not hinder the vehicle in the opposite direction, and the process of having to pull the vehicle backward first, pulling the vehicle stop 3 to a distance where the vehicle stop 3 can be laid down, and then laying down the vehicle stop 3 so that the vehicle can pass is eliminated, the functional coverage of the device is improved, a large amount of sand or other counterweights are arranged in the reset counterweight box 4, which can greatly increase the gravity of the bottom of the vehicle stop 3, so that the vehicle stop 3 can automatically reset from the laid-down state after the vehicle passes, thereby restoring the effect of stopping the vehicle in the front direction.
[0027] The inside of the bearing box 1 is provided with a blocking and buffering box 5, which can bear the blocking and buffering effect of the bearing box 1, and after the vehicle contacts the bearing box 1, the vehicle can be flexibly stopped under the action of the blocking and buffering box 5 and its internal structure, reducing the damage to the vehicle body caused by the direct collision of the vehicle with the vehicle stop 3, and the blocking and buffering box 5 and its internal structure can also block the laying down of the vehicle stop 3 and the reset counterweight box 4, thereby providing support for the vehicle stopping operation of the vehicle stop 3.
[0028] A group of buffering telescopic rods 6 are fixedly installed in the inside of the blocking and buffering box 5, the telescopic ends of each buffering telescopic rod 6 penetrate through the blocking and buffering box 5 and are slidably connected with the blocking and buffering box 5, when the vehicle stop 3 is laid down, the reset counterweight box 4 can press the buffering telescopic rod 6, at this time the buffering telescopic rod 6 will contract and buffer the laying down of the vehicle stop 3, so that the vehicle stop 3 can slow down the vehicle in the opposite direction and play a role in speed regulation, when the vehicle in the front direction contacts the vehicle stop 3, the buffering telescopic rod 6 can block the laying down of the vehicle stop 3 because the position of the blocking and buffering box 5 is fixed at this time, so that the vehicle stop 3 can stop the vehicle.
[0029] A top spring 7 is sleeved on the outer surface of each buffering telescopic rod 6, the two ends of each top spring 7 are fixedly connected with the blocking and buffering box 5 and the buffering telescopic rod 6 respectively, the top spring 7 provides elastic force for the telescoping of the buffering telescopic rod 6, so that the buffering telescopic rod 6 can effectively buffer the external force received by the vehicle stop 3 and the reset counterweight box 4, and the buffering telescopic rod 6 can be reset, thereby facilitating the continuous location operation of the buffering telescopic rod 6 on the reset counterweight box 4.
[0030] A reversing plate 16 is fixedly connected to the bottom surface of the reset counterweight box 4, and a support plate 17 is fixedly connected to the outer surface of the reversing plate 16. When the blocking buffer box 5 is upright, the vehicle stop 3 will fall over under the contact and push of the forward vehicle. At this time, the support plate 17 will rotate to a specific position and contact the slot in the limiting plate 18, thereby restricting the automatic reset of the vehicle stop 3 under the gravity of the reset counterweight box 4, keeping the vehicle stop 3 in a fallen state. Only when the blocking buffer box 5 rotates again can the contact between the limiting plate 18 and the support plate 17 be canceled, so that the vehicle stop 3 can be reset under the gravity of the reset counterweight box 4.
[0031] A limiting plate 18 is fixedly connected to the outer surface of the blocking buffer box 5. The limiting plate 18 has a slot inside, and the support plate 17 is adapted to the slot. The limiting plate 18 has sufficient space inside, and the snap-fit end of the support plate 17 has a certain elasticity. When the blocking buffer box 5 is in an upright state, after the vehicle stop 3 falls to a certain position, the support plate 17 can rotate into the limiting plate 18 and snap into the slot of the limiting plate 18 through elastic compression. At this time, the limiting plate 18 can limit the support plate 17. When the blocking buffer box 5 rotates, the limiting plate 18 will also rotate, thereby causing the support plate 17 to disengage from the snap-fit state, making it convenient for the vehicle stop 3 to reset.
[0032] An actuator strut 8 is fixedly connected inside the blocking buffer box 5. The actuator strut 8 passes through the bearing box 1 and is rotatably connected to the bearing box 1. The rotation of the actuator strut 8 can drive the blocking buffer box 5 to rotate. The rotation of the blocking buffer box 5 can change its own angle, thereby causing the buffer telescopic rod 6 to remove the limit on the reset counterweight box 4. At this time, when a vehicle traveling in the forward direction comes into contact with the vehicle stop 3, the vehicle stop 3 can be made to fall forward, thereby removing the vehicle blocking effect. After the vehicle passes, the actuator strut 8 rotates again to drive the blocking buffer box 5 to reset. At this time, the vehicle stop 3 will stand upright again under the gravity of the reset counterweight box 4, thereby performing the vehicle blocking and speed adjustment work again.
[0033] A rotating lever 9 is fixedly connected to the outer surface of the actuator strut 8, and an actuator cylinder 10 is fixedly installed inside the bearing housing 1. The actuator cylinder 10 is prior art and will not be described in detail in this application. When the actuator cylinder 10 is activated, its telescopic end can contact the rotating lever 9 and slowly push the rotating lever 9 to rotate. The rotation of the rotating lever 9 can drive the actuator strut 8 to rotate, thereby causing the blocking buffer housing 5 to tend to be upright. During the slow pushing process, the vehicle stop 3 will also slowly fall down with the contact of the vehicle, thereby slowing down the vehicle and playing a role in speed regulation.
[0034] A fixed sleeve 11 is fixedly connected to the outer surface of the actuator strut 8. A hinge block 12 is fixedly connected to the outer surface of the fixed sleeve 11. A rotating sleeve 13 is rotatably connected to the inside of the hinge block 12 via a pin. A sliding groove 14 is provided on the top surface of the bearing housing 1. When the operator selects the manual control device, the manual adjustment rod 15 can be inserted into the rotating sleeve 13, and then the manual adjustment rod 15 can be pushed in the sliding groove 14. The manual adjustment rod 15 can drive the actuator strut 8 to rotate, thereby adjusting the angle of the blocking buffer housing 5. The two ends of the sliding groove 14 have grooves. When the manual adjustment rod 15 slides to one end of the sliding groove 14, it can be pushed into the groove to fix the manual adjustment rod 15, thereby ensuring the stability of the vehicle stop 3 when it falls over. The attached drawings in this application are for reference only. The specific style should be based on the actual production.
[0035] The sliding groove 14 has a sliding connection to a manual adjustment rod 15, which is slidably connected to the rotating sleeve 13. The actuator cylinder 10 can drive and control the tilting of the wheel chock 3. If the actuator cylinder 10 is difficult to work normally in a specific environment, the operator can manually push the position of the manual adjustment rod 15 to control the device, which improves the convenience of the device and makes it easier for the operator to select the driving mode of the device according to the actual environment.
[0036] Working principle: The operator first installs the device in a suitable position. In the normally closed state, the vehicle stop 3 remains upright. When an oncoming vehicle passes by, it can automatically reverse and fall over upon contact with the vehicle stop 3. The buffer telescopic rod 6 can hinder the falling of the vehicle stop 3, thus slowing down the passage of oncoming vehicles. When a vehicle is passing by in the forward direction, the vehicle stop 3 will be difficult to fall over due to the limitations imposed by the buffer box 5 and the buffer telescopic rod 6. At this time, the vehicle stop 3 will have a vehicle-stopping effect, and the contact between the vehicle stop 3 and the vehicle achieves a flexible stopping operation. To allow forward vehicles to pass... When a vehicle is passing through, the actuator rod 8 can be rotated by the actuator cylinder 10 or the manual adjustment rod 15. The rotation of the actuator rod 8 can drive the blocking buffer box 5 to rotate. The rotation of the blocking buffer box 5 can remove the limit on the vehicle stop 3. At this time, the vehicle stop 3 will fall forward upon contact with the vehicle, thus facilitating the passage of vehicles in the forward direction. During the forward falling of the vehicle stop 3, the blocking buffer box 5 will slowly rotate under the push of the actuator cylinder 10, thus causing the vehicle stop 3 to slowly fall, thereby slowing down the passage of vehicles in the forward direction. This realizes the three-in-one vehicle blocking, stopping and speed regulation operation of the device, improving the applicability of the device.
[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
