Description

Technical Field

[0001] The utility model relates to the technical field of mine car fixing, and more particularly to a car stabilizing device suitable for cage transportation. Background Art

[0002] The cage is a commonly used hoisting system in mine shafts. During the cage transportation process, mine cars are used as material containers to transport ore, waste slag, equipment, materials, etc. In order to ensure that the mine car does not move during the operation of the cage after entering the cage, it is necessary to install car arresters at both ends of the two tracks at the bottom of the cage to fix the mine car. The car arrester will be installed at the bottom of the cage. When a vehicle enters the cage, the car arrester will clamp the wheels of the mine car to prevent it from falling freely or flying up. The method of using the cage is that when the mine car moves from the track to a fixed position, the car arresters on both sides of the track are flipped up and clamped on both sides of the mine car's moving wheels, fixing the mine car by clamping. However, since the moving wheels of the mine car are not flat, there will be bolts or grooves, etc., which make it difficult to fix them well. Moreover, when clamping both ends of the moving wheels, the mine car will still move on the track due to the shaking of the cage, resulting in the mine car not being able to be fixed well.

[0003] Chinese utility model patent application number CN214527562U discloses a cage-mounted vehicle arresting device comprising an external thrust mechanism and a cage-mounted vehicle arresting mechanism. The external thrust mechanism is disposed at the upper and lower shaft openings, and the cage-mounted vehicle arresting mechanism comprises a push rod, a pull rod, a center plate, a torsion spring, a vehicle arresting buffer mechanism, and a vehicle arresting claw. The push rod is connected to the pull rod, which is connected to the surface of the center plate. Driven by the push rod, the pull rod can generate a torque on the center plate. The torsion spring is connected to the bottom of the center plate, and the vehicle arresting claw is connected to the pull rod via a pin. This cage-mounted vehicle arresting device achieves a vehicle arresting effect by closing the vehicle arresting claw with a torsion spring. However, due to the high and narrow bottom of the mine car, the mine car can only be secured by clamping the moving wheels. However, since the moving wheels of the mine car are not flat, the mine car cannot be properly secured. Moreover, the mine car may move due to the shaking of the cage during its ascent.

[0004] Therefore, it is necessary to propose a vehicle stabilizing device suitable for cage transportation to solve the above problems. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-7 A vehicle stabilizing device suitable for cage transportation includes a fixed frame 101 and a fixed claw 102 arranged on the fixed frame 101, the fixed frame 101 is fixed in the cage, and the track 118 on the top of the fixed frame 101 is used for the mine car to enter and exit. A rotating rod 103 and a linkage rod 104 are rotatably connected to the fixed frame 101. The two ends of the rotating rod 103 are set as spline grooves, and the fixed claw 102 can slide on it. The driving head 116 on the linkage rod 104 is connected to the output end of the cylinder 117 and rotates by starting the cylinder 117. The linkage rod 104 is transmission-connected to the rotating rod 103 through the linkage assembly 115. The fixed claw 102 is slidably connected to the two ends of the rotating rod 103, and a compression chamber 105 is opened inside the fixed claw 102;

[0029] The fixed column is slidably connected with a trigger block 106 and a guide rod 107 that penetrates the compression chamber 105. The trigger block 106 and the guide rod 107 slide in the compression chamber 105. When the fixed claw 102 fixes the mine car, the trigger block 106 will first contact the moving wheel of the mine car. The guide rod 107 is located on one side of the trigger block 106. A return spring 108 is sleeved on the guide rod 107. The return spring 108 is fixedly connected to the trigger block 106 and the inner wall of the compression chamber 105. The top of the fixed claw 102 is symmetrically rotated and connected with a clamping claw 109. The clamping claw 109 is L-shaped. When the trigger block 106 moves through the guide rod 107, the clamping claw 10 One end of 9 moves along the strip groove 110, and the other end will clamp toward the moving wheel to fix it. A strip groove 110 is provided inside the trigger block 106, and one end of the clamping claw 109 slides in the strip groove 110. When the trigger block 106 moves, the clamping claw 109 fixed on the fixed claw 102 will be driven by the strip groove 110 to rotate. One end of the clamping claw 109 is slidably connected in the strip groove 110. One end of the clamping claw 109 is fixedly connected to a resistance slider 111. An arc surface is provided on the resistance slider 111. The resistance slider 111 is made of rubber. The arc surface fits with the moving wheel to strengthen the clamping ability of the moving wheel and prevent it from rotating.

[0030] The middle part of the rotating rod 103 is fixedly connected with a support plate 112 and a fixed head 113. The support plate 112 is used to fix the rotating rod 103 and a buffer spring 114. The support plate 112 is fixedly connected to the fixed frame 101. A buffer spring 114 is sleeved on the rotating rod 103. The buffer spring 114 is fixedly connected between the connecting plate, the fixed frame 101 and the fixed claw 102. The fixed mine car will shake during the movement of the cage due to unstable center of gravity. The shaking will be transmitted to the buffer spring 114, and the shaking will be slowed down by compression and tension of the buffer spring 114. The linkage assembly 115 and the drive head 116 are fixedly connected to the connecting rod. The internal rotation of the fixed frame 101 is connected to the cylinder 117. The output end of the cylinder 117 is rotatably connected to the drive head 116. The top of the fixed frame 101 is fixedly connected to the track 118.

[0031] Specifically, the linkage assembly 115 includes a center rod 119 and a connecting rod 120. The center rod 119 rotates with the rotation of the linkage rod 104. During rotation, the rotating rod 103 is driven to rotate through the connecting rod 120, thereby opening and closing the fixed claw 102. The connecting rod 120 is located at both ends of the center rod 119, and one end of the connecting rod 120 is connected to the fixed head 113.

[0032] Specifically, an open groove 121 corresponding to the fixing claw 102 is opened on the outer wall of the fixing frame 101. When the fixing claw 102 is opened, the fixing claw 102 will be received in the open groove 121. The rubber strip 122 in the open groove 121 acts as a cushion to prevent the rotating rod 103 from hitting the fixing frame 101 when it is opened. The rubber strip 122 is fixedly connected to the open groove 121.

[0033] Specifically, a rubber pad 123 is fixedly connected to one side of the fixing claw 102 . The rubber pad 123 , the rubber strip 122 and the resistance sliding block 111 are all made of rubber. Being made of rubber can increase friction and buffering capacity.

[0034] Specifically, anti-slip stripes are provided on the rubber pad 123 and the anti-sliding block 111 to increase friction and strengthen the fixation of the moving wheel.

[0035] In this embodiment, the device is installed in the cage, and the track 118 is used for the entry and exit of the mine car. When not in use, the cylinder 117 retracts, and the fixed claws 102 on both sides of the track 118 are opened, horizontally, and located in the open slots 121 on the fixed frame 101. When the mine car moves to the designated position on the track 118, the cylinder 117 is started, and the output end drives the linkage rod 104 to rotate through the driving head 116. The linkage rod 104 drives the linkage assembly 115 on the outer wall to transmit. The linkage assembly 115 is pushed to both sides by the connecting rod 120, so that the rotating rods 103 at both ends rotate, and the rotating rods 103 drive the fixed claws 102 to rotate. The fixed claws 102 on both sides of the track 118 clamp toward the moving wheels of the mine car, thereby completing the fixation.

[0036] When the fixed claw 102 moves toward the axis of the moving wheel, the trigger block 106 will first contact the axis of the moving wheel. After the trigger block 106 contacts the moving wheel, it will drive the guide rod 107 to slide in the compression chamber 105, causing the return spring 108 to compress. When the trigger block 106 moves, one end of the clamping claw 109 will slide along the strip groove 110, driving the other end to rotate, thereby clamping both sides of the moving wheel. A resistance block 111 is fixed to the clamping claw 109. The resistance block 111 has an arc surface that fits the moving wheel, thereby fixing the moving wheel and preventing it from rotating.

[0037] When unlocking is required, the output end of the cylinder 117 retracts, driving the linkage rod 104 to rotate in the opposite direction, causing the linkage assembly 115 to rotate in the opposite direction, and pulling the fixed head 113 on the rotating rod 103 toward the middle through the connecting rod 120. The rotating rod 103 drives the fixed claw 102 to open to both sides, and the trigger block 106 is reset by the extension of the reset spring 108. The clamping claws 109 on both sides are opened, thereby losing the fixation of the moving wheel. During the movement of the cage, the mine car may shake due to unstable center of gravity. The buffer springs 114 on both sides of the fixed claw 102 can slow down the shaking and keep it centered.

[0038] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
