Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of logistics and transportation equipment, and in particular to a braking device for a jackhammer. Background Technology
[0002] A ground jack, or simply "jack," is a type of transport device used in logistics warehouses to move goods within the warehouse. It is a convenient and compact transport tool that is commonly seen in logistics warehouses and is used for lifting and lowering using hydraulic jacks.
[0003] Existing pallet jacks, such as the one disclosed in utility model patent application number 201821982909.1, have a braking device. Their main structure includes a load-bearing arm, a hydraulic device, a steering arm, and a clamping device. One end of the load-bearing arm is connected to the hydraulic device, which is mounted on the steering arm. The steering arm is rotatably connected to the load-bearing arm, and the lower end of the steering arm is rotatably connected to a steering wheel via a rotating shaft. In use, when it is necessary to brake the pallet jack, the brake pedal is pressed down with the foot. The steering wheel is engaged in a groove and pressed against the rubber pad in the groove, thus braking the steering wheel. When the brake pedal is released, it returns to its original position under the action of a torsion spring.
[0004] However, most existing hand brakes lack braking devices or have braking devices that can only brake one wheel, and they mostly achieve braking through complex methods such as pneumatics and hydraulics, making them relatively cumbersome to use. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a braking device for a ground jack that not only facilitates installation on different ground jacks, improving the flexibility of the device, and simultaneously brakes both wheels of the ground jack, but also eliminates the need for a complex structure and utilizes mechanical transmission for braking.
[0006] This utility model discloses a braking device for a pallet breaker, comprising a support mechanism; it also includes a fixing mechanism, a pedal mechanism, a reset mechanism, a braking mechanism, and a tension spring. The fixing mechanism is mounted on the support mechanism to facilitate fixing the pallet breaker; the pedal mechanism is mounted on the support mechanism to facilitate stepping on it by the operator; the reset mechanism is mounted on the pedal mechanism to facilitate releasing the brake; the braking mechanism is mounted on the reset mechanism to brake the roller; and the tension spring is mounted on the reset mechanism to facilitate resetting the braking mechanism. The fixing mechanism facilitates connection of the device to the pallet breaker. When braking is required, the operator steps down on the pedal mechanism, which pulls the reset mechanism up and presses down on the braking mechanism to fix the roller, preventing it from continuing to rotate. When the brake needs to be released, the operator steps on the reset mechanism, which, along with the tension spring, causes the braking mechanism to reset.
[0007] Preferably, the support mechanism includes two sets of brackets, a central shaft, two sets of rollers, and a main shaft. Both sets of brackets have through holes. The central shaft is rotatably installed in the through holes of the two sets of brackets. Both sets of rollers are installed on the central shaft. The main shaft is installed on the central shaft and located between the two sets of rollers. The two sets of brackets connect the device to the two sets of rollers of the pallet jack, which improves the flexibility of the device and makes it easy to install on various pallet jacks.
[0008] Preferably, the fixing mechanism includes a first connecting shaft and a clamp. The first connecting shaft is installed between the two sets of brackets, and the clamp is rotatably installed on the first connecting shaft. The clamp is fixedly connected to the brackets by bolts, which facilitates the fixing of the device and prevents the device from rotating with the two sets of rollers.
[0009] Preferably, the pedal mechanism includes a second connecting shaft, pedal A, a protrusion, a pedal shaft, and two sets of edges. The second connecting shaft is installed between two sets of supports. Pedal A is rotatably mounted on the second connecting shaft, the protrusion is mounted on pedal A, the pedal shaft is rotatably mounted on pedal A, and both sets of edges are mounted on pedal A. When braking is required, the operator presses pedal A down. By setting the two sets of edges, the stress on pedal A is increased, making it more stable. Pressing down pedal A activates the reset mechanism and the braking mechanism.
[0010] Preferably, the reset mechanism includes two sets of connecting plates, a B pedal, and a brake shaft. Both sets of connecting plates are rotatably mounted on the pedal shaft. The bottom end of the B pedal is connected to the top end of the two sets of connecting plates, and the brake shaft is rotatably mounted between the two sets of connecting plates. When braking is required, the operator steps down on the A pedal. By setting two sets of edges, the stress on the A pedal is increased, making it more stable. The A pedal presses down to activate the reset mechanism and the braking mechanism.
[0011] Preferably, the braking mechanism includes a brake plate and two sets of brake blocks. The brake plate is rotatably mounted on the first connecting shaft and rotatably connected to the brake shaft. The top ends of the two sets of brake blocks are connected to the bottom ends of the brake plate. When the brake shaft descends, it causes the brake plate to flip forward, thereby causing the two sets of brake blocks to abut against the two sets of rollers, stopping the two sets of rollers from rotating and achieving the braking effect.
[0012] Preferably, the tension spring includes a tension spring body, a first pin, and a second pin. The tension spring body is mounted on a second connecting shaft, the first pin is mounted on the tension spring body and hooked onto the first connecting shaft, and the second pin is mounted on the tension spring body and hooked onto the brake shaft. The tension spring body is positioned by setting the first pin, and the brake shaft is easily driven to rebound by setting the tension spring body and the second pin, thereby resetting the braking mechanism and releasing the brake.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the device can be easily connected to the ground jack through the fixing mechanism. When braking is required, the operator steps down on the pedal mechanism, which pulls the reset mechanism up and presses down on the braking mechanism to fix the roller and prevent the roller from continuing to rotate. When the brake needs to be released, the reset mechanism is stepped on, and the reset mechanism and the tension spring drive the braking mechanism to reset. Attached Figure Description

Detailed Implementation
[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.
[0021] Example 1
[0022] This utility model discloses a braking device for a jackhammer, comprising a support mechanism 01; it also includes a fixing mechanism 02, a pedal mechanism 03, a reset mechanism 04, a braking mechanism 05, and a tension spring 06. The fixing mechanism 02 is mounted on the support mechanism 01 to facilitate fixing the jackhammer; the pedal mechanism 03 is mounted on the support mechanism 01 to facilitate stepping on it by the operator; the reset mechanism 04 is mounted on the pedal mechanism 03 to facilitate releasing the brake; the braking mechanism 05 is mounted on the reset mechanism 04 to brake the rollers; and the tension spring 06 is mounted on the reset mechanism 04 to facilitate resetting the braking mechanism 05. The support mechanism 01 includes two sets of brackets 11, a central shaft 12, two sets of rollers 13, and a main shaft 14. Both sets of brackets 11 have through holes, the central shaft 12 is rotatably mounted in the through holes of the two sets of brackets 11, both sets of rollers 13 are mounted on the central shaft 12, and the main shaft 14 is mounted on the central shaft 12 and located between the two sets of rollers 13. The fixing mechanism 02 includes a first connecting shaft 21 and a clamp 22. Shaft 21 is installed between two sets of brackets 11, and clamp 22 is rotatably installed on the first connecting shaft 21; pedal mechanism 03 includes a second connecting shaft 31, A pedal 32, protrusion 33, pedal shaft 34 and two sets of edges 35. The second connecting shaft 31 is installed between two sets of brackets 11, A pedal 32 is rotatably installed on the second connecting shaft 31, protrusion 33 is installed on A pedal 32, pedal shaft 34 is rotatably installed on A pedal 32, and both sets of edges 35 are installed on A pedal 32; reset mechanism 04 includes two sets of connecting plates 41, B pedal 42 and brake shaft 43. Both sets of connecting plates 41 are rotatably installed on pedal shaft 34, the bottom end of B pedal 42 is connected to the top end of the two sets of connecting plates 41, and brake shaft 43 is rotatably installed between the two sets of connecting plates 41; brake mechanism 05 includes brake plate 51 and two sets of brake blocks 52. Brake plate 51 is rotatably installed on the first connecting shaft 21 and rotatably connected to brake shaft 43, and the top end of the two sets of brake blocks 52 is connected to the bottom end of brake plate 51;During operation, firstly, two sets of brackets 11 connect the device to the two sets of rollers 13 of the pallet jack, improving the device's flexibility and facilitating installation on various pallet jacks. Bolts are used to secure the clamp 22 to the brackets 11, ensuring the device is fixed in place and preventing it from rotating with the rollers 13. When braking is required, the operator presses down on pedal A 32. Two sets of edges 35 increase the stress on pedal A 32, enhancing its stability. Pressing down on pedal A 32 activates the reset mechanism 04 and the braking mechanism 05. 2. The pedal shaft 34 descends, which in turn causes the two sets of connecting plates 41 to descend. The two sets of connecting plates 41 then cause the brake shaft 43 and brake mechanism 05 to descend. Simultaneously, the rotation of the two sets of connecting plates 41 causes pedal B 42 to lift. The descent of brake shaft 43 causes brake plate 51 to flip forward, thereby causing the two sets of brake blocks 52 to press against the two sets of rollers 13, preventing the rollers 13 from rotating and thus providing braking. When it is necessary to release the brake, the operator presses pedal B 42 downwards, causing pedal B 42 to reset the connecting plates 41, brake shaft 43, and pedal shaft 34.
[0023] Example 2
[0024] like Figures 1 to 5 As shown, this utility model discloses a braking device for a pallet breaker, based on embodiment 1. The tension spring 06 includes a tension spring body 61, a first pin 62, and a second pin 63. The tension spring body 61 is mounted on a second connecting shaft 31, the first pin 62 is mounted on the tension spring body 61 and hooked onto the first connecting shaft 21, and the second pin 63 is mounted on the tension spring body 61 and hooked onto the brake shaft 43. During operation, firstly, two sets of brackets 11 connect the device to the two sets of rollers 13 of the pallet breaker, improving the device's flexibility and facilitating installation on various pallet breaker types. Bolts are used to fix the clamp 22 to the brackets 11, facilitating device fixation and preventing the device from rotating with the two sets of rollers 13. When braking is required, the operator presses down on pedal A 32. By setting two sets of edges 35, the stress on pedal A 32 is increased, enhancing its stability. The A pedal 32 is pressed down, which activates the reset mechanism 04 and the braking mechanism 05. The A pedal 32 drives the pedal shaft 34 to descend, which in turn drives the two sets of connecting plates 41 to descend. The two sets of connecting plates 41 drive the brake shaft 43 and the braking mechanism 05 to descend. At the same time, the two sets of connecting plates 41 rotate, causing the B pedal 42 to lift up. The brake shaft 43 descends, causing the brake plate 51 to flip forward, so that the two sets of brake blocks 52 abut against the two sets of rollers 13, stopping the two sets of rollers 13 from rotating and thus achieving the braking effect. When it is necessary to release the brake, the operator presses the B pedal 42 down. The B pedal 42 drives the connecting plate 41, the brake shaft 43 and the pedal shaft 34 to reset. The tension spring body 61 is positioned by setting the first pin 62. The tension spring body 61 and the second pin 63 are set to facilitate the return of the brake shaft 43, thereby resetting the braking mechanism 05 and releasing the brake.
