Description

Technical Field

[0001] This utility model relates to a hydraulic wheel stopper for a trackless rubber-tired vehicle tank internal braking device, belonging to the field of mining machinery. Background Technology

[0002] Trackless rubber-tired vehicles are widely used in large mines. During the hoisting of cages in vertical shafts, electric internal car-stopping devices are generally selected. Common car-stopping devices use a motor-driven screw transmission method. This type of transmission has poor overload characteristics, poor environmental adaptability, and is easily jammed. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a hydraulic vehicle stopper for a trackless rubber-tired vehicle tank-mounted vehicle blocking device.

[0004] To achieve the above objectives, this utility model employs a hydraulic wheel stopper for a trackless rubber-tired vehicle tank-mounted vehicle blocking device, which includes a trolley installed on a ground rail, a slider installed on the ground rail, an extension arm cylinder installed on the trolley, and a wheel stopper cylinder connected to the trolley.

[0005] One end of the trolley is hinged to a connecting rod via a rotating arm. A wedge is installed at one end of the connecting rod, and the other end is hinged to a slider. The trolley, slider, connecting rod, and rotating arm form a slider-linkage mechanism. The extending arm cylinder is connected to the slider. The piston rod of the extending arm cylinder extends and retracts, driving the slider to move back and forth along the ground rail, thereby moving the slider-linkage mechanism to extend or retract the wedge. The stopping cylinder is used to drive the trolley to slide back and forth along the ground rail and control the extension and retraction of the piston rods of the extending arm cylinder and the stopping cylinder to achieve wedge blocking or wedge opening for passing vehicles.

[0006] As an improvement, the trolley is equipped with a slider guide rail, the slider is connected to the slider guide rail, and the boom cylinder drives the slider to move along the slider guide rail.

[0007] As an improvement, each tank-mounted vehicle-stopping device is equipped with two pairs of hydraulic vehicle stoppers. The two hydraulic vehicle stoppers are arranged in parallel on the inside of the wheelset of the trackless rubber-tired vehicle.

[0008] As an improvement, the boom cylinder is arranged on the front or rear side of the trolley.

[0009] Compared with the prior art, the hydraulic wheel stopper of the trackless rubber-tired vehicle tank of this utility model has a compact structure and occupies little space. Utilizing the soft characteristics of the hydraulic system, it can work stably under jammed conditions, which improves reliability. It is also more adaptable to harsh environments with water spray and coal slag pollution, thus improving operational safety. Attached Figure Description

[0020] Example 1

[0021] like Figure 1 As shown, a hydraulic wheel stopper for a trackless rubber-tired vehicle tank includes a trolley 1, a slider 2, a rotating arm 3, a connecting rod 4, a wedge 5, an extended arm cylinder 6, a wheel stop cylinder 7, and a ground rail 8, etc.

[0022] The stopping cylinder 7 and the ground rail 8 are fixed on the bottom plate of the cage. The trolley 1 is installed on the ground rail 8. The piston rod of the stopping cylinder 7 is connected to the trolley 1 and can drive the trolley 1 to slide back and forth along the ground rail 8.

[0023] The slider 2 is installed on the ground rail 8 and can slide freely along the ground rail 8. The trolley 1 is equipped with a boom cylinder 6. The piston rod of the boom cylinder 6 is connected to the slider 2, which can drive the slider 2 to slide back and forth relative to the trolley 1 along the ground rail 8, and can also move along the ground rail 8 with the trolley 1.

[0024] One end of the rotating arm 3 is hinged to point A on the trolley 1, and the other end of the rotating arm 3 is hinged to point B on the connecting rod 4. The slider 2 is hinged to point C on the connecting rod 4. The trolley 1, the rotating arm 3, the connecting rod 4 and the slider 2 form a slider-linkage mechanism.

[0025] The piston rod of the boom cylinder 6 extends and retracts, causing the slider 2 to move relative to the trolley 1, driving the slider linkage mechanism to move, which in turn drives the wedge block 5 fixed on the connecting rod 4 to extend or retract. When the wedge block 5 extends, i.e., when the wedge block 5 is placed horizontally, the lane is blocked. Figure 1 When wedge 5 retracts, i.e., when wedge 5 is placed to the side, the lane is opened, as follows: Figure 2 ;

[0026] The piston rods of the boom cylinder 6 and the stop cylinder 7 are sequentially controlled to extend and retract, driving the wedge block 5 to perform the operation of blocking or allowing passing vehicles to pass.

[0027] Specifically, the process of implementing wedge blocking is as follows:

[0028] (1) Control the piston rod of the stop cylinder 7 to extend, and the trolley 1 moves to the front end;

[0029] (2) Control the piston rod of the boom cylinder 6 to extend, drive the slider linkage mechanism, and drive the wedge block 5 to unfold. The wedge block 5 is placed horizontally to stop the car.

[0030] (3) Control the piston rod of the stop cylinder 7 to retract, the trolley 1 drives the wedge block 5 to move backward to the wheel of the trackless rubber-wheeled vehicle and stop, thus realizing the wedge blocking operation.

[0031] The process of implementing the wedge-opening passage is as follows:

[0032] (1) Control the piston rod of the stop cylinder 7 to extend, drive the trolley 1 to move the wedge block 5 forward to the front end, and stop;

[0033] (2) Control the piston rod of the boom cylinder 6 to retract, and the wedge block 5 to retract to the side of the channel, and open the wedge to pass.

[0034] Example 2

[0035] Example 1 is a basic structure of the hydraulic wheel stop. A slider guide rail 9 can also be provided on the trolley 1, and the movement trajectory of the slider 2 can be freely set by the slider guide rail 9.

[0036] like Figure 3 As shown, a hydraulic wheel stopper for a trackless rubber-tired vehicle tank includes a trolley 1, a slider 2, a rotating arm 3, a connecting rod 4, a wedge 5, an extended arm cylinder 6, a wheel stop cylinder 7, and a ground rail 8, etc. The trolley 1 is equipped with a slider guide rail 9.

[0037] The stopping cylinder 7 and the ground rail 8 are fixed on the bottom plate of the cage. The trolley 1 is installed on the ground rail 8. The piston rod of the stopping cylinder 7 is connected to the trolley 1 and can drive the trolley 1 to slide back and forth along the ground rail 8.

[0038] The trolley 1 is equipped with the boom cylinder 6, the piston rod of the boom cylinder 6 is connected to the slider 2, and the slider 2 is limited by the slider guide rail 9;

[0039] One end of the rotating arm 3 is hinged to point A on the trolley 1, and the other end of the rotating arm 3 is hinged to point B on the connecting rod 4. The slider 2 is hinged to point C on the connecting rod 4. The trolley 1, the rotating arm 3, the connecting rod 4 and the slider 2 form a slider-linkage mechanism.

[0040] The piston rod of the boom cylinder 6 extends and retracts, causing the slider 2 to slide on the slider guide rail 9, which in turn drives the slider linkage mechanism to move. This causes the wedge block 5, fixed on the linkage 4, to extend or retract. When the wedge block 5 extends, i.e., when it is horizontal, the lane is blocked. Figure 3 When wedge 5 retracts, i.e., when wedge 5 is placed to the side, the lane is opened, as follows: Figure 4 ;

[0041] The extension and retraction of the piston rods of the boom cylinder 6 and the stop cylinder 7 are sequentially controlled to drive the wedge block 5 to perform the operation of blocking or allowing passing vehicles to pass. The operation process is the same as in Example 1.

[0042] Example 3

[0043] When a pair of front derailers or a pair of rear derailers need to be arranged inside the trackless rubber-tired wheel pair, a parallel scheme with the two derailers back to back can be adopted. The original two trolleys are connected as one unit, and the original two sliders are connected as one unit. The control arm cylinder 6 and the derailer cylinder 7 can synchronously drive the movement of the two wedges.

[0044] like Figure 5 As shown, a hydraulic wheel stop for a trackless rubber-tired vehicle tank uses a scheme of two wheel stops connected in parallel, including a trolley 1, a slider 2, a rotating arm 3, a connecting rod 4, a wedge 5, an extended arm cylinder 6, a wheel stop cylinder 7, a ground rail 8, a slider guide rail 9, a second rotating arm 10, a second connecting rod 11, a second wedge 12, and a second ground rail 13, etc.

[0045] The stopping cylinder 7, the ground rail 8, and the second ground rail 13 are fixed on the bottom plate of the cage. The ground rail 8 and the second ground rail 13 are parallel to each other. The trolley 1 is installed on the ground rail 8 and the second ground rail 13. The piston rod of the stopping cylinder 7 is hinged to the trolley 1, which can drive the trolley 1 to slide back and forth along the ground rail 8. The trolley 1 is equipped with a boom cylinder 6. The piston rod of the boom cylinder 6 is connected to the slider 2. The slider 2 is limited by the ground rail 8 and the second ground rail 13.

[0046] One end of the rotating arm 3 is hinged to point A on the trolley 1, and the other end is hinged to point B on the connecting rod 4. A wedge 5 is fixed on the connecting rod 4, and the other end of the connecting rod 4 is hinged to the slider 2 at point C. The trolley 1, connecting rod 4, rotating arm 3, and slider 2 form a first slider linkage mechanism. Similarly, one end of the second rotating arm 10 is hinged to point D on the trolley 1, and the other end is hinged to point E on the second connecting rod 11. A second wedge 12 is fixed on the second connecting rod 11, and the other end of the second connecting rod 11 is hinged to the slider 2 at point F. The trolley 1, second connecting rod 11, second rotating arm 10, and slider 2 form a second slider linkage mechanism.

[0047] The piston rod of the boom cylinder 6 extends and retracts, causing the slider 2 to move, synchronously driving the first slider linkage mechanism and the second slider linkage mechanism to move, which in turn drives the wedge block 5 and the second wedge block 12 to achieve the extension or retraction of the boom. Figure 5 As shown.

[0048] The extension and retraction of the piston rods of the boom cylinder 6 and the blocking cylinder 7 are sequentially controlled to drive the wedge block 5 and the second wedge block 12 to perform the blocking and opening operations on passing vehicles. The operation process is the same as in Example 1.

[0049] Example 4

[0050] In the above embodiments 1 to 3, the boom cylinder 6 is arranged at the rear end of the trolley 1; the boom cylinder 6 can also be arranged at the front end of the trolley 1, with the extension and retraction directions of the piston rod of the boom cylinder 6 being opposite, and the action result of the stopper is the same as in embodiment 3.

[0051] like Figure 6 As shown, a hydraulic wheel stop for a trackless rubber-tired vehicle tank is provided, featuring a scheme of two wheel stops operating in parallel. An extendable arm cylinder 6 is positioned at the front end of the trolley 1. The piston rod of the extendable arm cylinder 6 extends and retracts, causing the slider 2 to move. This synchronously drives the first slider linkage mechanism and the second slider linkage mechanism, which in turn move the wedge block 5 mounted on the connecting rod 4 and the second wedge block 12 mounted on the second connecting rod 11, thus enabling the wheel stops to extend or retract. Figure 6 As shown.

[0052] The extension and retraction of the piston rods of the boom cylinder 6 and the blocking cylinder 7 are sequentially controlled to drive the wedge block 5 and the second wedge block 12 to perform the blocking and opening operations on passing vehicles. The operation process is the same as in Example 3.
