Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting brakes, in particular to a clearance adjusting device for a brake of a tire-type lifting hoist. Background Art
[0002] A tire crane, also known as a tire crane or a tire crane, is a boom-swivel crane that uses a tire chassis to travel. The main feature of a tire crane is that it can travel on a tire chassis, so it can be used on flat ground without outriggers for small loads and low-speed travel. This type of crane is widely used in various operating scenarios, including docks, ports, construction sites, etc.
[0003] The brake of a tire crane is one of the important safety components of the crane. Its main function is to ensure that the moving parts of the crane can be reliably fixed when it is necessary to stop or keep the crane and its load in a stationary state during the lifting process to prevent the crane or its load from accidentally moving or falling. In order to ensure the normal operation and safety of the brake, regular maintenance and inspection should be carried out, including adjusting the brake clearance, etc.
[0004] At present, with the increase of years of use, the clearance adjustment mechanism at the bottom of the tire crane hoist brake is seriously worn, the adjustment effect deteriorates or even fails, resulting in uneven left and right clearances when the brake is opened, and unilateral wear of the brake disc often occurs, which greatly affects the braking effect and safety. In addition, the original brake adjustment device is not practical in design, time-consuming and labor-intensive to adjust, and the adjustment effect is poor. The brake is severely worn after a long period of time and the braking effect cannot be guaranteed. In order to ensure safety, it can only be replaced, which increases the operating cost. Utility Model Content
[0005] In view of the technical problem that the brake clearance is difficult to adjust, the utility model aims to provide a brake clearance adjustment device for a tire-type crane hoist, which has a simple structure and is easy to operate, improves the braking performance of the brake, and saves operating costs.
[0006] The utility model provides a brake clearance adjustment device for a tire-type crane hoist, comprising an adjustment base and an adjustment rod passing through the adjustment base, wherein the adjustment rod has an external thread, and the adjustment rod is provided with a first fastener and a second fastener matched with the thread, and the first fastener and the second fastener are distributed on both sides of the adjustment base.
[0007] Furthermore, a first gasket is sleeved on the adjustment rod between the first fastener and the adjustment base.
[0008] Furthermore, a second gasket is sleeved on the adjustment rod between the second fastener and the adjustment base.
[0009] Furthermore, the adjustment base is made of square stainless steel.
[0010] Furthermore, the first fastener and the second fastener are both nuts.
[0011] Furthermore, the adjusting rod is a bolt.
[0012] The beneficial effects of the utility model are that the utility model has a simple structure and is easy to operate, and can efficiently adjust the clearance of the tire crane brake, timely eliminating the safety hazards caused by the increase in the service life of the brake, so that the brake continues to operate safely and reliably, ensuring the safety of the equipment, and solving the technical problem that the original clearance adjustment device can only be replaced due to severe wear and tear due to long service life, thereby saving costs. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.
[0014] Figure 1 It is a three-dimensional structural schematic diagram of a specific implementation method of the utility model.
[0015] In the figure: 1-first fastener, 2-adjusting base, 3-adjusting rod, 4-second fastener. DETAILED DESCRIPTION
[0016] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0017] Example 1
[0018] like Figure 1 The utility model provides a brake gap adjustment device for a tire-type crane hoist, including an adjustment base 2 and an adjustment rod 3 passing through the adjustment base 2, the adjustment rod 3 has an external thread, and the adjustment rod 3 is provided with a first fastener 1 and a second fastener 4 matched with the thread, and the first fastener 1 and the second fastener 4 are distributed on both sides of the adjustment base 2.
[0019] A first gasket is sleeved on the adjustment rod 3 between the first fastener 1 and the adjustment base 2. A second gasket is sleeved on the adjustment rod 3 between the second fastener 4 and the adjustment base 2. The first gasket and the second gasket function to disperse the pressure between the two fasteners and the adjustment base 2.
[0020] The adjusting base 2 is made of square stainless steel. The first fastener 1 and the second fastener 4 are both nuts. The adjusting rod 3 is a bolt. Bolts and nuts are easy to obtain and inexpensive, and are easy to manufacture.
[0021] The application cases of the utility model in actual hoisting hoist brake clearance adjustment are:
[0022] During the operation of the tire-type crane, due to the wear and failure of the original adjustment device, when the brake was on, there was a large gap between the left brake pad and the brake disc, while the right brake pad was close to the brake disc and was severely worn, which seriously affected the braking effect.
[0023] The utility model is used to adjust the brake clearance. The specific method is to weld the adjustment base 2 to the brake assembly, rotate the first fastener 1 and the second fastener 4 to make the lower end of the adjustment rod 3 rest against the support body, further rotate the first fastener 1 and the second fastener 4 to make the adjustment rod 3 move along the direction of the adjustment rod 3 and then drive the brake assembly to deviate until the clearance between the left brake pad and the right brake pad and the brake disc is the same, and the clearance adjustment is completed.
[0024] Although the present invention is described in detail by referring to the accompanying drawings and in combination with the preferred embodiments, the present invention is not limited thereto.
