Description
Technical Field
[0001] This utility model relates to the field of handling tools, and in particular to a portable crowbar cart. Background Technology
[0002] Crowbars, which utilize the lever principle to help lift heavy objects, are commonplace. They are typically curved, featuring a relatively flat lifting bar and a slanted grip connected to it. To use them, the front end of the lifting bar is first inserted under the heavy object. Then, using the bend in the grip where it connects to the lifting bar as a fulcrum, the operator pulls down on the grip to lift the object. However, existing crowbars are generally only suitable for lifting heavy objects; they are not suitable for, or inconvenient for, moving the lifted object. Utility Model Content
[0003] This invention addresses the aforementioned problems by proposing a portable crowbar vehicle.
[0004] The technical means adopted in this utility model are as follows:
[0005] A portable crowbar cart includes a crowbar body and a first roller disposed at the front end of the crowbar body. The crowbar body includes a gripping rod for an operator to hold and a prying rod for prying up heavy objects. It also includes a support rod mounted on the gripping rod and a second roller disposed at the lower end of the support rod.
[0006] After the crowbar lifts the heavy object, the first roller and the second roller are a certain distance apart and can be supported on the ground together.
[0007] Furthermore, the height at which the support rod connects to the grip rod is adjustable.
[0008] Furthermore, the support rod has multiple mounting holes along its length, and the gripping rod has a support rod insertion groove; through holes are provided on both sides of the support rod insertion groove; the through holes can correspond to different mounting holes on the support rod and be fastened together with bolts.

[0022] like Figure 1 As shown, the portable crowbar vehicle disclosed in this utility model includes a crowbar body 1 and a first roller 2 disposed at the front end of the crowbar body 1. The crowbar body 1 includes a gripping rod 10 for the operator to hold and a prying rod 11 for prying up heavy objects. It also includes a support rod 3 mounted on the gripping rod 10 and a second roller 4 disposed at the lower end of the support rod 3.
[0023] After the crowbar lifts the heavy object, the first roller 2 and the second roller 4 are a certain distance apart and can be supported on the ground together.
[0024] Specifically, such as Figure 1 As shown, the crowbar cart disclosed in this application includes a crowbar body 1 and a first roller 2 disposed at the front end of the crowbar body 1. The crowbar body 1 includes a gripping rod 10 for the operator to hold and a prying rod 11 for inserting under a heavy object and prying it up. The gripping rod 10 and the prying rod 11 are set at a certain angle. The first roller 2 is provided at the connection position between the gripping rod 10 and the prying rod 11. When using the crowbar cart to pry up a heavy object, the prying rod 11 is inserted under the heavy object, and the first roller 2 serves as a support point. By pressing down on the gripping rod 10, the heavy object can be pried up. In this embodiment, a support rod 3 is also installed on the gripping rod 10, and a second roller 4 is provided at the lower end of the support rod 3. After the crowbar cart pries up the heavy object, the first roller 2 and the second roller 4 are a certain distance apart and are supported on the ground together.
[0025] The crowbar cart disclosed in this application, due to the addition of a support rod 3 and a second roller 4, facilitates the transfer of heavy objects. Specifically, the process of using the crowbar cart disclosed in this utility model to pry up and transfer heavy objects is as follows: First, insert the pry bar under one end of the heavy object, press down by holding the rod, and use the first roller as a support point to lift one end of the heavy object. At this time, the second roller at the lower end of the support rod does not need to contact the ground. Preferably, the second roller contacts the ground, so that the crowbar cart forms two-point contact with the ground to reduce the workload of the operator (the operator only needs to press the holding rod and does not need to worry about excessive pressing force or excessive tilting angle of the crowbar cart to separate from the heavy object). When the operator uses the crowbar cart to lift the heavy object... After one end of the object is pried up, other operators place a ground tank (transfer wheel, transfer trolley) under the pried end. Then, the pry bar is used to lower the pried end of the object onto the ground tank. Next, the pry bar is used to pry up the other end of the object, so that the second roller at the bottom of the support rod contacts the ground. At this point, both ends of the object are lifted (one end on the ground tank, the other end on the pry bar). By dragging the pry bar, the object can be easily transferred short distances. During the transfer, the pry bar is supported by two sets of rollers on one side, distributing the weight of the object to the two wheels, reducing the pressure on the wheels. At the same time, the shift in the center of gravity facilitates the forward movement of the object, thereby reducing the workload of the operators.
[0026] Furthermore, the height at which the support rod 3 connects to the grip rod 10 is adjustable.
[0027] Specifically, the connection height between the support rod 3 and the grip rod 10 is adjustable, which makes it convenient for different operators to use, or convenient for prying heavy objects to different heights.
[0028] Furthermore, the support rod 3 is provided with a plurality of mounting holes 30 along its length, and the gripping rod 10 is provided with a support rod insertion groove 12; the support rod insertion groove 12 is provided with through holes on both sides; the through holes can correspond to different mounting holes 30 on the support rod 3 and be fastened together by bolts 14.
[0029] Specifically, in this embodiment, the support rod 3 adopts a rod structure with a rectangular cross-section, and multiple mounting holes 30 are machined along the length of the support rod 3. The gripping rod 10 can adopt a rod structure with a circular or square cross-section, and a rectangular groove is machined on the gripping rod 10 to form a support rod insertion groove 12. The support rod 3 can be inserted into the support rod insertion groove 12. Through holes are machined on both sides of the support rod insertion groove 12 on the gripping rod 10. By adjusting the tilt angle of the gripping rod 10, the through holes on the gripping rod 10 correspond to the mounting holes at different heights on the support rod 3. Then, the bolts 14 can pass through the through holes 12 and the corresponding mounting holes 30 in sequence, thereby connecting the support rod 3 and the gripping rod 10. That is, the support rod 3 is connected to the mounting holes 30 at different heights through the through holes, thereby realizing the adjustment of the connection height between the support rod 3 and the gripping rod 10, so as to facilitate use by different operators.
[0030] Furthermore, it also includes a support rod limiting rod 6;
[0031] One end of the support rod limiting rod 6 is hinged to the gripping rod 10, and the other end of the support rod limiting rod 6 is provided with an elongated hole 60;
[0032] The elongated hole 60 of the support rod limiting rod 6 is opposite to the mounting hole 30 on the support rod 3 and is locked with bolts.
[0033] Specifically, it also includes a support rod limiting rod 6. One end of the support rod limiting rod 6 has a through hole, and the other end has an elongated hole 60. The end of the support rod limiting rod 6 with the through hole is hinged to the gripping rod 10 by a bolt, so that the support rod limiting rod 6 can swing around the bolt. This allows the elongated hole 60 at the other end of the support rod limiting rod 6 to be aligned with the mounting hole 30 on the support rod 3. The end of the support rod limiting rod 6 with the elongated hole 60 is then fastened to the support rod 3 by a bolt. Because the support rod limiting rod 6 is provided, and both ends of the support rod limiting rod 6 are connected to the gripping rod 10 and the support rod 3 respectively, a triangular structure is formed. That is, the support rod limiting rod 6 can restrict the rotation of the support rod 3 relative to the gripping rod 10, thereby ensuring the stability when using the pry bar cart.
[0034] Furthermore, a rope hook 5 for hooking ropes is also installed in the mounting hole 30 on the side of the support rod 3 near the second roller 4.
[0035] Specifically, in this embodiment, the mounting hole 30 on the lower end of the support rod 3, near the second roller 4, can be used to hook a rope. This allows the rope to be hooked into the mounting hole during the transfer of heavy objects using a crowbar, and the rope applies a horizontal pulling force F to the crowbar, thus making the transfer of heavy objects more convenient and effortless. Preferably, a bolt (i.e., the rope hook 5 is a bolt) is installed in the mounting hole. The two ends of the bolt extend a certain length from both sides of the support rod 3 to form a rope hook portion, and the end of the rope can be hooked onto it to apply a horizontal pulling force F to the crowbar.
[0036] Furthermore, the end of the grip rod 10 is also provided with a hand handle 15, which is rotatably connected to the grip rod 10.
[0037] Specifically, a hand handle 15 is provided at the end of the grip rod 10. The operator can easily grasp the grip rod 10 with the hand handle 15 so as to pry up heavy objects with a crowbar or transfer heavy objects with a crowbar. Preferably, the hand handle 15 is located at the end of the grip rod 10 and is rotatably connected to the axis of the grip rod 10, so as to facilitate the adjustment of the angle between the hand handle 15 and the grip rod 10, and facilitate the operator to perform corresponding operations.
[0038] Furthermore, the second roller 4 is a swivel wheel.
[0039] Specifically, the second roller 4 can adopt a general roller structure. Preferably, the second roller 4 adopts a caster wheel, which facilitates the adjustment of direction during the transfer of heavy objects by a pry bar cart.
[0040] Furthermore, both the first roller 2 and the second roller 4 are made of polyurethane.
[0041] Specifically, both the first roller 2 and the second roller 4 are made of polyurethane. This is because the actual application scenarios of crowbars are increasingly in buildings where the ground is already completed. The general transportation and use of equipment can damage the ground. In this embodiment, the rollers of the crowbar are made of polyurethane. Polyurethane wheels are elastic and can play a certain role in shock absorption (even better than pneumatic wheels). They have good grip, are not easy to slip, are more wear-resistant, have good comfort performance, and can better protect the ground and make it safer.
[0042] Furthermore, a reinforcing plate 16 is laser-welded between the gripping rod 10 and the prying rod 11.
[0043] Specifically, in this embodiment, the gripping rod 10 and the pry bar 11 are set at a certain angle, and the gripping rod 10 and the pry bar 11 are reinforced with reinforcing plates 16 by laser welding on both sides. Preferably, the reinforcing plates 16 are made of arc-shaped metal plates. By welding the metal reinforcing plates, the strength of the pry bar vehicle is improved and the load-bearing capacity of the pry bar vehicle is increased.
[0044] Furthermore, such as Figure 2 As shown, when the support rod 3 is inserted into the support rod insertion slot 12 and fixedly connected to the gripping rod 10, the end of the support rod 3 with the second roller 4 is inclined to the side away from the first roller 2.
[0045] Specifically, such as Figure 2 As shown, when the support rod 3 is inserted into the support rod insertion slot 12 to be fixedly connected with the gripping rod 10, the support rod 3 is inclined at a certain angle to the vertical direction, thereby increasing the distance between the first roller and the second roller, thus improving the load-bearing capacity and running stability of the crowbar cart. The crowbar cart disclosed in this utility model may have a width of the support rod insertion slot 12 (width along the gripping rod axis) equal to or slightly larger than the width of the support rod 3 (width along the gripping rod axis), thereby restricting the rotation of the support rod 3 through the support rod insertion slot 12, thus ensuring the smooth operation of the crowbar cart. Preferably, as... Figure 2 As shown, a support rod limiting rod 6 is set between the support rod 3 and the gripping rod 10. The support rod limiting rod 6 locks the support rod 3 and the gripping rod 10, so that the support rod 3 can be tilted at a certain angle to the vertical direction, increasing the distance between the first roller and the second roller, thereby improving the smooth operation of the crowbar cart; at the same time, due to the supporting effect of the support rod limiting rod 6, the strength of the crowbar cart is improved, and its service life is extended.
[0046] 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.
