Description

Technical Field

[0001] The utility model relates to the technical field of rescue tools, in particular to a hydraulic roof supporter. Background Art

[0002] A hydraulic roof support is a hydraulic demolition tool, mostly used to rescue victims trapped in a confined environment. Its main components are a cylinder and a piston push rod. It often uses a motor pump, electric pump, etc. as the power source, and relies on hydraulic pressure to push the piston push rod out of the cylinder to achieve the support function.

[0003] In car accident rescue, the hydraulic roof support can support, stabilize or lift parts of the vehicle as needed to open a channel for emergency rescue. In disaster rescue such as fire, earthquake and other building collapse, the device can be used to support and fix dangerous objects, and can also be used to lift heavy objects and expand space. The device is an essential rescue tool for fire brigades, traffic police teams and other disaster relief departments.

[0004] The top of the existing hydraulic roof supporter is usually fixed with a rubber pad. However, when the user uses it, the rubber pad is often worn due to the heavy volume of the heavy objects to be handled. After long-term use, it cannot be replaced, resulting in a poor use effect of the roof supporter and low practicality of the design. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0024] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0027] Combined with Figure 1 and 2 A hydraulic top supporter of the present embodiment includes a hydraulic top supporter body 1, a rubber pad 2 is provided on the top of the hydraulic top supporter body 1, and a fixing seat 3 for fixing the rubber pad 2 is also provided on the top of the hydraulic top supporter body 1. The rubber pad 2 is arranged on the upper end surface of the fixing seat 3, and a plurality of plug posts 4 are evenly distributed on the upper end surface of the fixing seat 3. The upper ends of the plug posts 4 are relatively sharp. When installing the rubber pad 2, it can be directly pressed onto the fixing seat 3 and fixed by the plurality of plug posts 4. A positioning ring 5 is arranged around the outer side of the rubber pad 2, and the positioning ring 5 is connected to the fixing seat 3. The positioning ring 5 is mainly arranged to limit the installation position of the rubber pad 2 to ensure that the force applied to the rubber pad 2 is evenly transmitted to the fixing seat 3.

[0028] The main body 1 of the hydraulic support device can replace the rubber pad 2, and the replacement operation of the rubber pad 2 is very convenient and the structure is relatively simple. In particular, the rubber pad 2 does not need to be designed into a complex structure to adapt to the replacement operation, and can still be designed into a cylindrical shape in a traditional way without grooving.

[0029] As a preferred solution of the utility model, the positioning ring 5 is provided with a connecting plate 6 which is magnetically connected to the bottom surface of the fixing seat 3, and the connecting plate 6 is provided with a circular opening which is adapted to the hydraulic support body 1. When the connecting plate 6 is magnetically connected to the bottom surface of the fixing seat 3, the upper end of the positioning ring 5 is located in the middle position of the rubber pad 2 (taking the new rubber pad 2 as an example).

[0030] As a preferred solution of the utility model, the positioning ring 5 is magnetically connected to the fixing seat 3. When disassembling the rubber pad 2, the positioning ring 5 can be removed from the fixing seat 3 first, thereby improving the disassembly efficiency of the rubber pad 2. On this basis, prying grooves 10 are provided on both sides of the bottom of the rubber pad 2. The prying grooves 10 can be formed on site by manually cutting the bottom edge of the rubber pad 2 with a knife. The bottom of the connecting plate 6 is magnetically connected to a pry bar 11 that cooperates with the prying groove 10. The prying end of the pry bar 11 extends through the prying groove 10 into between the rubber pad 2 and the fixing seat 3, so that the rubber pad 2 that needs to be replaced can be quickly pushed upwards.

[0031] As a preferred solution of the utility model, for example, in order to facilitate pushing the positioning ring 5 to control the state of the magnetic connection, operating parts 7 are protruded on both sides of the positioning ring 5, and the operating parts 7 are semicircular protrusions. The movement of the positioning ring 5 can be controlled by controlling the operating parts 7 on both sides with two hands at the same time.

[0032] As a preferred solution of the utility model, it also includes a measuring ruler 8 that is slidably connected to the outer peripheral surface of the positioning ring 5 up and down, and the scale of the measuring ruler 8 is set along the axial direction of the positioning ring 5. The user can measure the distance between the upper end of the rubber pad 2 and the upper end of the positioning ring 5 according to the measuring ruler 8, thereby judging the degree of wear of the rubber pad 2.

[0033] As a preferred solution of the utility model, the top of the measuring ruler 8 is horizontally rotatably connected to an upper pressure plate 9. When measurement is required, the upper pressure plate 9 is rotated to the top of the rubber pad 2 so as to abut against the upper end of the rubber pad 2 when the measuring ruler 8 is lowered, thereby ensuring the accuracy of the measurement result. When measurement is not required, the upper pressure plate 9 is rotated to the outside of the rubber pad 2 and the measuring ruler 8 can be lowered to the lowest position at this time.

[0034] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
