Abstract
Description
Technical Field
[0001] This utility model relates to the field of dummy lifting equipment technology, and in particular to a dummy lifting and transfer device. Background Technology
[0002] In existing technologies, such as the dummy lifting device disclosed on the Chinese patent website with publication number CN209010044U, although the problem of dummy lifting has been solved, the following shortcomings still exist:
[0003] To prevent tipping during transport, most dummies are placed lying down in the truck bed. However, this can cause dragging issues when using existing hoisting devices. Since the hook lifts the dummy's head, and the hook is centered on the hoisting device, the dummy's feet may bump against the edge of the device's base as the hoisting is nearing completion. This can also cause the dummy's center of gravity to shift off-center, resulting in instability.
[0004] When transporting a dummy using this device, its head is suspended, leaving its feet dangling in the air. This causes the feet to wobble due to the device's movement and vibrations. Even when the feet are placed on the base, precise control is difficult to achieve: either the head shakes and the feet slip on the base, or the dummy wobbles as a whole with its feet dangling. Furthermore, since the dummy's weight is based on that of a real person, this wobbling easily leads to tipping during transport. Utility Model Content
[0005] Based on the existing technical problems, this utility model proposes a dummy hoisting and transfer device.
[0006] The present invention discloses a dummy hoisting and transfer device, including a base with casters, a bracket vertically fixedly installed on the upper surface of one end of the base, a steel cable with a hook on the top of the bracket, one end of the steel cable passing through a pulley installed on the bracket and extending to the back of the bracket, and a motor for winding the steel cable is also provided on the back of the bracket, the motor being powered by a battery fixedly installed at the bottom of the bracket.
[0007] The base has right-angled plates that are hinged outwards on both sides, and a locking mechanism is provided at the front end of the two right-angled plates to lock the right-angled plates together.
[0008] The upper surface of the right-angle plate is provided with a restraint mechanism for binding and restraining the dummy's legs and feet.
[0009] Preferably, a limiting groove is provided on the outer side of the hinge joint between the base and the right-angle plate, so that the right-angle plate is limited when it rotates outward to the maximum angle.
[0010] Through the above technical solution, the limiting groove can limit the maximum rotation angle of the right-angle plate, preventing the problem of the right-angle plate's rotation angle being difficult to control when one person is operating it.
[0011] Preferably, the locking mechanism includes a locking plate rotatably installed at the joint of one of the right-angle plates, the surface of the locking plate having a toothed groove, and a locking plate fixedly installed at the joint of the upper surface of the other right-angle plate, which engages with the toothed groove.
[0012] When the two right-angle plates are rotated and spliced, the locking plate is driven into the card plate to achieve a fixed action.
[0013] The above technical solution employs a principle similar to ratchet and pawl, with the tooth grooves interlocking with the locking plate, effectively locking the plate.
[0014] Preferably, the pin at the rotation center of the card plate extends to the lower surface of the right-angle plate, and a torsion spring is sleeved on the surface of the pin, with both ends of the torsion spring being fixedly connected to the pin and the surface of the right-angle plate, respectively.
[0015] Through the above technical solution, the torsion spring keeps the locking plate always moving towards the locking plate, effectively preventing the locking plate from detaching from the locking plate when shaking.
[0016] Preferably, the restraint mechanism includes a telescopic rod hinged to the upper surface of the right-angle plate, and a restraint strap with Velcro is fixedly installed on the telescopic end surface of the telescopic rod. The restraint strap wraps around the dummy's legs, and the binding action is achieved by Velcro.
[0017] With the above technical solution, after the dummy is bound by the restraint straps, when it shakes during transport, it will be pulled back by the telescopic rod, completely limiting the dummy's shaking amplitude within the telescopic rod's extension and retraction range.
[0018] The beneficial effects of this utility model are as follows:
[0019] 1. By setting right-angle plates that are hinged outward on both sides of the base, collisions between the base 1 and the dummy can be avoided. The right-angle plates are hinged outward and unfolded. The hook can first lift the dummy's head, and then the omnidirectional wheels can be used to move the transport device step by step to the position of the dummy's feet until the dummy's feet are completely lifted.
[0020] 2. By setting a locking mechanism, the right-angle plate can be reset and fixed after the dummy is lifted, which facilitates long-distance transportation.
[0021] 3. By setting up a restraint mechanism, the problem of the dummy shaking during transportation can be effectively prevented. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Reference Figure 1-3 A dummy hoisting and transporting device includes a base 1 with casters 2. A bracket 3 is vertically fixedly installed on the upper surface of one end of the base 1. A steel cable 4 with a hook 41 is provided on the top of the bracket 3. One end of the steel cable 4 passes through a pulley 42 installed on the bracket 3 and extends to the back of the bracket 3. A motor 5 for winding the steel cable 4 is also provided on the back of the bracket 3. The motor 5 is powered by a battery 51 fixedly installed at the bottom of the bracket 3.
[0028] To prevent the base 1 from causing injury to the dummy due to bumps or collisions, the two sides of the base 1 are designed as right-angled plates 6 that hinge outwards, creating an openable front end that completely prevents contact between the base 1's edge and the dummy. Furthermore, a limiting groove 61 is provided on the outer side of the hinge point between the base 1 and the right-angled plate 6. When the right-angled plate 6 rotates outwards to its maximum angle, it is restrained. The limiting groove 61 restricts the maximum rotation angle of the right-angled plate 6, preventing issues with uncontrollable rotation angles when operated by a single person.
[0029] By setting right-angle plates 6 that are hinged outward on both sides of the base 1, collisions between the base 1 and the dummy can be avoided. The right-angle plates 6 are hinged outward and unfolded. The hook 41 can first lift the dummy's head, and then the transport device can be moved step by step to the position of the dummy's feet through the casters 2 until the dummy's feet are completely lifted.
[0030] To prevent the right-angle plate 6 from swaying during transport and causing difficulty in controlling the transport trajectory, a locking mechanism is provided at the front end splicing point of the two right-angle plates 6 to lock the right-angle plates 6 together.
[0031] Specifically, it is implemented as follows: the locking mechanism includes a locking plate 7 rotatably installed at the splicing point of one of the right-angle plates 6, the surface of the locking plate 7 having a toothed groove 71, and a locking plate 72 fixedly installed at the splicing point of the upper surface of the other right-angle plate 6, which engages with the toothed groove 71.
[0032] When the two right-angle plates 6 rotate and connect, they cause the locking plate 72 to engage with the latching plate 7, thus securing the plate. Employing a principle similar to a ratchet and pawl, the toothed groove 71 engages with the locking plate 72, effectively locking the latching plate 7.
[0033] Furthermore, the pin 73 at the rotation center of the locking plate 7 extends to the lower surface of the right-angle plate 6. A torsion spring 74 is sleeved on the surface of the pin 73, and both ends of the torsion spring 74 are fixedly connected to the pin 73 and the surface of the right-angle plate 6, respectively. The torsion spring 74 keeps the locking plate 7 always springing towards the locking plate 72, effectively preventing the locking plate 7 from disengaging from the locking plate 72 when shaking.
[0034] By setting a locking mechanism, the right-angle plate 6 can be reset and fixed after the dummy is lifted, which facilitates long-distance transportation.
[0035] In order to effectively control the amplitude of the dummy's swaying, a restraint mechanism for binding and restraining the dummy's legs and feet is provided in the middle of the upper surface of the right-angle plate 6.
[0036] Specifically, this is achieved as follows: The restraint mechanism includes a telescopic rod 8 hinged to the upper surface of the right-angle plate 6. A restraint strap 81 with Velcro is fixedly installed on the telescopic end of the telescopic rod 8. The restraint strap 81 wraps around the dummy's legs, and the Velcro secures the dummy. After the dummy is restrained, the restraint strap 81 will pull back when the dummy sways during transport, completely limiting the dummy's swaying within the telescopic range of the rod 8.
[0037] By setting up a restraint mechanism, it is possible to effectively prevent the dummy from shaking during transportation.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
