Description

Technical Field

[0001] This utility model relates to the field of anti-sports car technology, specifically, to an anti-sports car. Background Technology

[0002] In mining operations, ore often needs to be transferred over short distances, such as between the mining face and the hoist or between the crushing station and the flotation machine feed. Since the ore production points are relatively scattered, miners use wheelbarrows to transfer the ore when going down into the mine. These wheelbarrows are small in size, flexible in steering, and can move freely in narrow tunnels and gaps between equipment. They are a classic transfer method based on efficiency, safety, and adaptability to mining operations.

[0003] However, during the descent process, if the cart is moved onto a downward-sloping track, and a worker trips or accidentally lets go, the cart may slide down the inclined track, causing the cart and the ore to tip over or shift. Therefore, a runaway prevention system is proposed. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this utility model provide a runaway prevention system, which solves the technical problem in the prior art where, when workers push a cart on an inclined track in a mine, if their hands slip and they lose control of the cart, the cart may slide down the inclined track, causing the cart to become uncontrollable.

[0005] According to one aspect, at least one embodiment of the present invention provides a runaway brake, including a chassis panel, a push handle, and a caster wheel mounted on the bottom of the chassis panel. The push handle is fixedly mounted on the chassis panel. The system also includes a mounting bracket, a brake stop plate, a pull-back blocking assembly, and a control assembly. Two mounting brackets are fixedly mounted on the side of the chassis panel, and the brake stop plate is slidably mounted on each of the two mounting brackets. Two pull-back blocking assemblies are provided for fixing the brake stop plate after it is pulled back away from the caster wheel. Two control assemblies are provided, and the control assembly is mounted on the push handle for controlling the contact and movement of the brake stop plate with the caster wheel.

[0006] Furthermore, the pullback blocking assembly includes a telescopic spring, a positioning rod, and a fixing assembly. A plurality of the telescopic springs are fixedly installed on the inner side wall of the mounting frame, and the side of the brake plate is fixedly connected to the plurality of the telescopic springs. The positioning rod is fixedly installed on the inner side wall of the mounting frame, and the fixing assembly is disposed on the mounting frame.

[0007] Furthermore, the fixing component includes a fixing block and a fixing rod. The fixing block is fixedly installed on the side of the brake plate, and the fixing rod is slidably installed through the top of the mounting bracket. The top of the fixing block is provided with a fixing hole that matches the bottom of the fixing rod.

[0008] Furthermore, the control component includes an upper grip, a lower grip, and a drive component. The upper grip is fixedly mounted on the side of the push handle, and the lower grip is rotatably mounted on the side of the push handle via a pivot. The upper grip and the lower grip are connected by a tension spring, and the drive component is mounted on the fixed rod.

[0009] Furthermore, the drive assembly includes a rack and a drive gear ring. The rack is fixedly mounted on the side of the fixed rod, and the drive gear ring is fixedly mounted on the rotating shaft. The rack meshes with the drive gear ring.

[0010] Furthermore, a protective cover is detachably installed on the side of the fixing rod, and both the rack and the drive gear ring are located inside the protective cover.

[0011] Furthermore, when the side of the brake plate is in contact with the side of the positioning rod, the bottom end of the fixing rod and the fixing hole of the fixing block are located in the same vertical position.

[0012] Furthermore, a connecting rod is fixedly installed between the two brake plates.

[0013] The beneficial effects of this utility model are as follows: In this invention, when a worker pushes the trolley, they do so by gripping the lower and upper handles. At this time, the brake plate can be fixed by the pull-back blocking component, thus moving the brake plate away from the caster wheel. When the worker releases their hand, the lower handle is released from the pressure of the worker's hand, and the control component and the fixing blocking component can then release the control of the brake plate, causing it to come into contact with the caster wheel and apply friction braking to the caster wheel. Thus, when the worker leaves the trolley, the brake plate can limit the trolley's movement. Attached Figure Description

[0022] like Figures 1-4 As shown, this invention illustrates a runaway vehicle protection device according to one embodiment, comprising a vehicle platform 1, a push handle 2, and a universal wheel 3 mounted on the bottom of the vehicle platform 1. The push handle 2 is fixedly mounted on the vehicle platform 1. The device also includes a mounting bracket 4, a brake stop plate 5, a pull-back blocking assembly, and a control assembly. Two mounting brackets 4 are fixedly mounted on the side of the vehicle platform 1, and brake stop plates 5 are slidably mounted on both mounting brackets 4. Two pull-back blocking assemblies are provided to fix the brake stop plate 5 after it is pulled back away from the universal wheel 3. Two control assemblies are provided and are mounted on the push handle 2 to control the contact and movement of the brake stop plate 5 with the universal wheel 3.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, when pushing the trolley, the operator first uses the control component and the pull-back blocking component to move the brake plate 5 away from the caster wheel 3 on the mounting frame 4. The pull-back blocking component includes a telescopic spring 6, a positioning rod 7, and a fixing component. Several telescopic springs 6 are fixedly installed on the inner wall of the mounting frame 4, and the side of the brake plate 5 is fixedly connected to several telescopic springs 6. The positioning rod 7 is fixedly installed on the inner wall of the mounting frame 4. The fixing component is set on the mounting frame 4 and includes a fixing block 8 and a fixing rod 9. The fixing block 8 is fixedly installed on the side of the brake plate 5, and the fixing rod 9 is slidably installed through the mounting frame 4. The top of the fixed block 8 is provided with a fixing hole that matches the bottom of the fixed rod 9. The control component includes an upper grip 10, a lower grip 11 and a drive component. The upper grip 10 is fixedly installed on the side of the push handle 2. The lower grip 11 is rotatably installed on the side of the push handle 2 via a rotating shaft 16. The upper grip 10 and the lower grip 11 are connected by a tension spring 12. The drive component is set on the fixed rod 9. The drive component includes a rack 13 and a drive gear ring 14. The rack 13 is fixedly installed on the side of the fixed rod 9. The drive gear ring 14 is fixedly installed on the rotating shaft 16. The rack 13 meshes with the drive gear ring 14.

[0024] Specifically, the operator holds the upper handle 10 and the lower handle 11 with both hands respectively. It should be noted that the rotating shaft 16 is rotatably mounted on the side of the push handle 2, and the center of the lower handle 11 is fixedly connected to the rotating shaft 16. The tension spring 12 is installed between the upper handle 10 and the lower handle 11. Therefore, when the operator holds and squeezes the lower handle 11, the lower handle 11 can compress the tension spring 12, which in turn rotates through the rotating shaft 16. The rotating shaft 16 then drives the drive gear ring 14 to rotate, and the drive gear ring 14 drives the rack 13 that meshes with it to move downward. The rack 13 then drives the fixing rod 9 to move downward, thereby inserting it into the fixing hole of the fixing block 8 on the side of the brake stop plate 5. At this time, the brake stop plate 5 compresses the telescopic spring 6 and moves away from the universal wheel 3, which can push the cart forward.

[0025] If the worker releases their grip, the tension spring 12, under the action of resetting, causes the lower handle 11 to rotate in the opposite direction, which in turn causes the rotating shaft 16 and the drive gear ring 14 to rotate in the opposite direction. This causes the rack 13 to move the fixing rod 9 upward, and the fixing rod 9 to disengage from the fixing hole of the fixing block 8. During the resetting process of the telescopic spring 6, the brake plate 5 is pressed forward and moves forward on the mounting bracket 4, thereby adhering to the universal wheel 3 and applying friction braking to it. This stops the trolley or slows down the universal wheel 3, giving the worker time to react before the trolley tipps over and pull it back.

[0026] After pulling, because a connecting rod 15 is fixedly installed between the two brake plates 5, the worker can hook the connecting rod 15 with their foot to move the two brake plates 5 backward. When the side of the brake plate 5 is in contact with the side of the positioning rod 7, the bottom end of the fixing rod 9 is in the same vertical position as the fixing hole of the fixing block 8. After pulling back until the side of the brake plate 5 is in contact with the side of the positioning rod 7, the worker can then grasp the lower handle 11 again to move the fixing rod 9 down and insert it into the fixing hole of the fixing block 8, thereby pushing the cart.

[0027] Furthermore, a protective cover 17 is detachably installed on the side of the fixed rod 9, and the rack 13 and the drive gear ring 14 are both located inside the protective cover 17. It should be noted that a vertical through groove is opened on the side of the protective cover 17, and the rotating shaft 16 passes through the vertical through groove. Therefore, when the fixed rod 9 moves up and down, the protective cover 17 will also move synchronously. At this time, the movement will not be blocked by the rotating shaft 16. The protective cover 17 can play a certain protective role for the rack 13 and the drive gear ring 14. Moreover, the staff can regularly maintain and lubricate the rack 13 and the drive gear ring 14, and maintain the telescopic spring 6 or the tension spring 12.

[0028] Working principle: When pushing the trolley, the operator holds the upper handle 10 and the lower handle 11 with both hands respectively. When the operator holds and squeezes the lower handle 11, the lower handle 11 can compress the tension spring 12 and rotate through the rotating shaft 16. The rotating shaft 16 drives the drive gear ring 14 to rotate. The drive gear ring 14 drives the rack 13 that meshes with it to move down. The rack 13 drives the fixing rod 9 to move down, thereby inserting it into the fixing hole of the side fixing block 8 of the brake stop plate 5. At this time, the brake stop plate 5 compresses the extension spring 6 and moves away from the universal wheel 3, which can push the trolley forward.

[0029] If the worker releases their grip, the tension spring 12, under the action of resetting, causes the lower handle 11 to rotate in the opposite direction, which in turn causes the rotating shaft 16 and the drive gear ring 14 to rotate in the opposite direction, thereby causing the rack 13 to move the fixing rod 9 upward. The fixing rod 9 then disengages from the fixing hole of the fixing block 8. During the resetting process of the telescopic spring 6, it presses the brake plate 5 forward and moves it forward on the mounting bracket 4, thereby adhering to the caster wheel 3 and applying friction braking to it, thereby stopping the trolley or slowing down the caster wheel 3.

[0030] It should be added that the brake damper 5 has an anti-slip rubber pad on the side facing the universal wheel 3. The surface of the anti-slip rubber pad has anti-slip texture, which can increase the frictional resistance with the universal wheel 3 and enhance the braking effect.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
