Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary hook bracket and belongs to the field of wheeled lifting machinery. Background Art
[0002] As a lifting device, the crane is installed on a special chassis equipped with pneumatic tires. During operation, the lifting of heavy objects is achieved by retracting and extending the lifting hook. For lighter loads and higher speed requirements, an auxiliary hook is used to assist in lifting (the auxiliary hook is generally single-rate or double-rate). After the operation is completed, the auxiliary hook is generally recovered into the auxiliary hook bracket.
[0003] like Figure 1 , Figure 2 , Figure 3 As shown, the auxiliary hook bracket of the existing crane is generally welded to the side of the crane frame. Because there is a covering walkway above the frame, in order to achieve the placement of the auxiliary hook and the flatness of the walkway, a round hole is opened on the walkway, and a covering circular plate fixed by fixing bolts is added. Among them, the number 100 is the crane frame, the number 200 is the auxiliary hook bracket, the number 300 is the covering circular plate, and the number 400 is the auxiliary hook. When placing the auxiliary hook 400, remove the fixing bolts and open the covering circular plate 300 on the walkway. After the placement is completed, the covering circular plate 300 is installed back to the original position by bolts for work safety.
[0004] The problems existing in the auxiliary hook bracket of the existing crane are as follows:
[0005] (1) If Figure 3 As shown, each time the auxiliary hook 400 is placed, the bolts need to be removed to open the covering circular plate 300 on the walkway, and then it needs to be closed after the placement is completed, and the fixing bolts need to be tightened. The placement takes a long time and the user convenience is low.
[0006] (2) During driving, if the road conditions are bad, the auxiliary hook 400 will vibrate up and down due to inertia, and may hit the cover plate 300 on the platform, causing the risk of wear on the cover plate 300 and the upper part of the auxiliary hook 400.
[0007] (3) Due to the development of overseas markets, the universal chassis between different countries and regions are slightly different, so the position of the connecting bracket may be different. For the auxiliary hook bracket welded on one side of the frame, different universal chassis need to design different positions, which increases the design and processing costs. The welded bracket on the frame cannot be adjusted during assembly, and the assembly requires high precision. The frame is heavy and it is difficult to adjust during assembly.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0042] like Figure 5 , Figure 6As shown, an auxiliary hook bracket 20 includes an auxiliary hook bracket body 1 and a detachable component. The auxiliary hook bracket body 1 is assembled on the side of the boom bracket 10 above the vehicle frame, and the auxiliary hook bracket body 1 has a chamber for accommodating the auxiliary hook; the detachable component acts between the auxiliary hook and the auxiliary hook bracket body 1, and is used to fix the auxiliary hook on the auxiliary hook bracket body 1.
[0043] A preferred embodiment of the auxiliary hook bracket body of the above embodiment is given below:
[0044] like Figure 4 As shown, the auxiliary hook bracket body 1 includes a hollow mounting component and a connecting component; the mounting component is used to assemble the auxiliary hook, and when the auxiliary hook is placed on the mounting component, the front hook-shaped structure of the auxiliary hook passes through the mounting component, and the rear columnar component of the auxiliary hook is confined in the mounting component, and the two are fixed together by a detachable component; the connecting component is fixed between the mounting component and the side of the boom bracket 10.
[0045] A further solution is that the inner cavity cross-section of the mounting component is wide at the top and narrow at the bottom, and the narrow portion at the bottom limits the auxiliary hook.
[0046] Preferred solution: The mounting component is composed of a circular tube 1-1 and an arc plate 1-4 located on the bottom surface of the circular tube 1-1 and extending inwardly, and the arc plate 1-4 is used to hold the auxiliary hook to prevent the auxiliary hook from falling.
[0047] It should be noted that the shape of the mounting component is not limited to the above-mentioned fixing method of a round tube plus an arc plate, and may also be a conical or other configuration of the auxiliary hook bracket.
[0048] Further solutions: Figure 4 , Figure 5 As shown, a pair of ear plates are provided on the top surface of the circular tube 1-1, which are opposite to each other and extend vertically upward. The through holes on the ear plates are on the same axis as the hanging holes of the auxiliary hooks in the mounting components, and are used for mounting detachable components.
[0049] A preferred embodiment of the above embodiment regarding the connecting component is given below:
[0050] like Figure 4 As shown, the connecting component is composed of a bracket 1-2 and a rib plate 1-3 in a C-shaped structure; the bracket 1-2 is welded to the outer peripheral surface of the mounting component, and the rib plate 1-3 is welded in the bracket 1-2 on the one hand and welded to the outer peripheral surface of the mounting component on the other hand.
[0051] Further solutions: Figure 6 As shown, the bracket 1 - 2 is provided with a through hole and is fixed to the side of the boom bracket 10 by a bolt group 30 .
[0052] A preferred embodiment of the above embodiment regarding the detachable component is given below:
[0053] like Figure 5 As shown, the detachable parts are composed of a connecting piece and a disassembling piece; the connecting piece connects the auxiliary hook and the auxiliary hook bracket body 1 together to prevent the auxiliary hook from moving up and down on the auxiliary hook bracket body 1, and the disassembling piece is installed on the connecting piece to prevent the connecting piece from falling off from the auxiliary hook and the auxiliary hook bracket body 1.
[0054] Further solutions: Figure 5 As shown, the connecting part is a pin shaft 2, and the disassembly part is an R-type card 3 used in conjunction with the pin shaft 2. The R-type cards 3 on both sides are used to limit the axial movement of the axle pin 2; when using and placing the auxiliary hook, only the two R-type cards 3 and the pin shaft 2 need to be removed, which greatly shortens the time required for placing the auxiliary hook and increases the convenience of user use.
[0055] It should be noted that the pin shaft and R-type clip in the above solution can be replaced with a chain and a lap buckle, or a stepped shaft plus a single R-type clip to limit the up and down movement of the auxiliary hook.
