As shown in fig. 1-3, the utility model provides a mining compound sliding car arrester with adjustable car stopping distance, which comprises an underframe 1, a track 12 and a wheel block linkage mechanism 2, wherein the track 12 and the wheel block linkage mechanism 2 are both fixed on the underframe 1; the wheel chock linkage mechanism 2 comprises a front wheel chock mechanism 5, a rear wheel chock mechanism 6, a wheel chock rotating shaft, a slidable bearing 3 and a hydraulic driving system 4; the hydraulic driving system 4 comprises a horizontal movement hydraulic driving mechanism and a rotary movement hydraulic driving mechanism 8; the front wheel chock mechanism 5 and the rear wheel chock mechanism 6 respectively comprise a left wheel chock, a right wheel chock, a crank 10, a connecting rod 9 and a rotary motion hydraulic driving mechanism 8, one end of the crank 10 is connected with the rotary motion hydraulic driving mechanism 8, a crank block is fixed at the other end of the crank 10, two ends of the crank block are respectively connected with the connecting rod 9, the connecting rod 9 is respectively connected with the left wheel chock and the right wheel chock, and the left wheel chock and the right wheel chock are both fixed on a wheel chock rotating shaft; the bottom of the sliding bearing is connected with the other end of a rotary motion hydraulic driving mechanism 8, and the sliding bearing 3 is connected with the horizontal movement hydraulic driving mechanism and driven by the horizontal movement hydraulic driving mechanism to horizontally slide on the track 12. The horizontal movement hydraulic driving mechanism comprises a hydraulic cylinder and a hydraulic push rod, the hydraulic cylinder is fixed on the underframe 1, and the hydraulic push rod is connected with the side direction of the sliding bearing 3. The hydraulic push rod is connected with the sliding bearing 3 in a hinged mode. A first slideway is provided on the side of the rail 12, on which the slidable bearing 3 is slidably fixed. A second slideway is arranged on the base frame 1, and the sliding bearing 3 is fixed on the second slideway in a sliding manner. One of the connecting angles between the crank 10 and the connecting rod is larger than or equal to a straight angle, and the other connecting angle is smaller than or equal to a straight angle.
The mining compound sliding car arrester with the adjustable car arresting distance is further explained by taking the example that the rail car 13 enters the car arresting distance from the rear wheel chock as an example. The mining compound sliding car arrester with the adjustable car stopping distance is installed at a position needing accurate car stopping in the middle of a track 12 through an underframe 1, foundation bolt holes are formed in the bottom of the track 12, and the mining compound sliding car arrester can be fixed to a foundation through bolts and transmits vertical and horizontal car stopping loads to the foundation. The chassis 1 is provided with short rails 12 connected to the outer rails 12.
The rail vehicle 13 with a certain wheelbase A runs to the car arrester, a front system can judge that the vehicle is required to be arrested through signals in advance when the rail vehicle reaches the front system, the front wheel fender mechanism 5 is closed, the rear wheel fender mechanism 6 is opened, the rail vehicle 13 enters the car arrester through the rear wheel fender mechanism 6, because the front wheel fender mechanism 5 is in the car arresting state, the front wheel stops when meeting the front wheel fender mechanism 5, and then the rear wheel fender mechanism 6 is closed, the rail vehicle 13 is in the accurate car arresting state. When the vehicle needs to be parked after the follow-up work of disassembling the vehicle and the like is finished, the front wheel chock mechanism 5 is opened, the vehicle arrester is in a parking state, and the rail vehicle 13 with the wheelbase A can leave from the front wheel chock mechanism 5.
When the rail vehicle 13 with another wheelbase B (B is less than A) needs to be stopped, the system sends a signal to the car stopper in advance, the car stopper obtains an instruction to actuate the horizontal displacement hydraulic driving mechanism 7, and drives two groups (4 in total) of sliding bearings 3, wheel stoppers and wheel stopper rotating shafts 11 to simultaneously and horizontally actuate towards the inner side, because the crank 10 and the connecting rod 9 are hinged at the bottom of the wheel stopper, and the rotary motion hydraulic driving mechanism 8 is hinged at the bottom of the sliding bearings 3, the crank 10, the connecting rod 9, the wheel stoppers and the rotary motion hydraulic driving mechanism 8 simultaneously move towards the inner side, and the horizontal direction action is stopped when the car stopping distance of the rail vehicle 13 with the wheelbase B is reached, namely the function of adjusting the car stopping distance is completed. And then the front wheel chock is closed, the rear wheel chock is opened, the vehicle with the wheelbase B enters the vehicle arrester from the rear wheel chock, the front wheel stops when meeting the closed front wheel chock mechanism 5, then the rear wheel chock mechanism 6 is closed, and the vehicle with the wheelbase B finishes accurate vehicle arresting. When the vehicle needs to be parked after the follow-up work of disassembling the vehicle and the like is finished, the front wheel chock mechanism 5 is opened, the vehicle arrester is in a parking state, and the rail vehicle 13 with the wheelbase B can leave from the front wheel chock mechanism 5.
When the vehicle stopping and releasing functions of the rail vehicle with the wheel base B (B is less than A) are finished firstly and then the vehicle stopping and releasing functions of the rail vehicle 13 with the wheel base A are entered, the horizontal action of the mechanism is opposite to the action, namely, the front wheel chock and the rear wheel chock are adjusted to the vehicle stopping state with the wheel base B firstly, and then the front wheel chock and the rear wheel chock are pulled to the vehicle stopping state with the wheel base A through the horizontal action of the horizontal hydraulic driving mechanism.
4-5, the initial conditions set as required for the proper functioning of the mechanism of the connecting rod 9 with respect to the crank 10 concerned are accounted for: according to the operation principle of the device, the same group of wheel blocks which are linked must rotate inwards or outwards simultaneously around respective rotating shafts so as to realize the functions of stopping or releasing the vehicle. On the one hand, as can be seen from the operation principle of the crank 10 and link 9 mechanism, if the drive is applied to the link 9, the crank 10 and link 9 mechanism has dead points when the transmission angle is zero, so the patent applies the drive to the crank 10 to effectively avoid the problem. On the other hand, in order to achieve the same set of wheel blocks of the crank 10 and connecting rod 9 mechanism to be capable of rotating inwards or outwards simultaneously to achieve the requirements of the vehicle stopping or releasing function, as can be seen from fig. 1, the driving forces of the crank 10 to the connecting rod must be opposite, i.e. the driving forces F1 and F2 must be directed towards the inner side or the outer side of the mechanism simultaneously to reverse the moment formed by the driving forces F1 and F2 on the respective wheel blocks. At the upper part of the crank 10 and the connecting rod 9, included angles alpha 1 and alpha 2 formed by the crank 10 and the two connecting rods 9 are larger than or equal to a straight angle (180 degrees) and smaller than or equal to a straight angle.
If the included angles α 1 and α 2 formed by the crank 10 and the two connecting rods 9 at the upper part of the connecting rod 9 of the crank 10 do not satisfy a condition of being larger than or equal to a flat angle and a condition of being smaller than or equal to a flat angle, taking one of the conditions as an example for explanation, when a hydraulic driving force is also applied to the crank 10, both α 1 and α 2 are larger than the flat angle, and the driving forces F1 and F2 formed by the crank 10 on the connecting rods 9 are in the same direction, the moments formed by the driving forces F1 and F2 on the respective wheel gears are in the same direction, so that the running directions of the same group of wheel gears are the same, and obviously, the functional requirements of the device cannot be met. Meanwhile, the track 12 is arranged on the inner side of the wheel chock, and the wheel chock running inwards cannot act due to the limit of the track 12, so that self-locking is formed. For the other situation, when the included angles α 1 and α 2 formed by the crank 10 and the two connecting rods 9 on the upper part of the connecting rod 9 of the crank 10 are both smaller than a straight angle, the normal operation of the mechanism cannot be satisfied and self-locking occurs in the same principle.
Through the analysis, the sufficient requirements for the normal movement of the device are as follows: on the upper part of the connecting rod 9 of the crank 10, included angles alpha 1 and alpha 2 formed by the crank 10 and the two connecting rods 9 are larger than or equal to a straight angle and smaller than or equal to a straight angle.
