Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a splash protection device for a pickaxe machine. Background Technology

[0002] In existing technologies, old roads and buildings often require jackhammers for breaking up concrete. However, when jackhammers break up concrete, they generate a lot of noise and dust, and the concrete blocks they break up are easily scattered everywhere, posing a great safety hazard.

[0003] Therefore, it is necessary to propose a splash protection device for pickaxe machines to solve the above problems. Utility Model Content

[0004] Technical problem to be solved: The purpose of this utility model is to provide a splash prevention device for a pickaxe to solve the problems mentioned in the background art, such as the loud noise and dust generated by existing pickaxes when breaking concrete, and the easy splashing of the excavated concrete blocks, which pose a great safety hazard.

[0005] Technical Solution: To achieve the above objectives, this utility model is implemented through the following technical solution: A splash guard for a pickaxe, comprising a flexible rubber cylinder sleeved on the outside of the pickaxe, an iron wire fixedly installed on the upper part of the flexible rubber cylinder, the other end of the iron wire being fixedly connected to the pickaxe, and fixing rings fixedly installed on both the left and right sides of the pickaxe; a sliding rod is slidably fitted inside the fixing ring along the axial direction, a baffle is fixedly installed at the upper end of the sliding rod, and the lower end is fixedly connected to the lower part of the flexible rubber cylinder, and a tension spring is sleeved on the sliding rod between the fixing ring and the baffle, with both ends of the tension spring being fixedly connected to the fixing ring and the baffle respectively.

[0006] Preferably, the two wires and the two slide bars are arranged in a cross shape.

[0007] Preferably, the lower part of the slide rod is bent towards the side close to the flexible rubber cylinder, and a connecting plate is welded to the lower end of the flexible rubber cylinder, and the connecting plate is bolted to the flexible rubber cylinder.

[0008] Preferably, the flexible rubber cylinder is a multi-section folded corrugated pipe structure with a spiral steel wire skeleton embedded in the pipe wall.

[0009] Beneficial effects: Compared with the prior art, this utility model provides a splash prevention device for a pickaxe. This splash prevention device has a unique structure and is easy to use. During operation, the tension spring drives the sliding rod to move axially along the fixed ring, so that the lower end of the rubber cylinder is in close contact with the working surface, forming a closed working space. At this time, the fragments generated by crushing are completely confined inside the rubber cylinder, avoiding the risk of splashing. The cross-shaped layout of the wire and the sliding rod forms a two-way fixing structure, ensuring that the rubber cylinder remains stable in position during violent vibration. In embodiment 2, the flexible rubber cylinder is set as a multi-section folded corrugated pipe structure, with a spiral steel wire skeleton embedded in the pipe wall, which maintains axial extensibility and improves radial impact resistance. This device directly blocks the path of fragment splashing through the dynamic sealing mechanism of the rubber cylinder. Compared with traditional unprotected operation, the safety factor of personnel and equipment at the construction site is significantly improved. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Example 1: This Example 1 provides a splash guard for a pickaxe machine, which has a unique structure. Please refer to [link / reference]. Figure 1 As shown, the device includes a flexible rubber cylinder 2 fitted around the outside of the pickaxe 1. A wire 3 is fixedly installed on the upper part of the flexible rubber cylinder 2, and the other end of the wire 3 is tied to the pickaxe head. Fixing rings 4 are fixedly installed on both sides of the pickaxe head. The fixing rings 4 can be installed in various ways, such as welding the fixing rings 4 to the pickaxe head. A sliding rod 5 is slidably fitted inside the fixing ring 4 along the axial direction. A baffle 6 is fixedly installed at the upper end of the sliding rod 5, and the lower end is fixedly connected to the lower part of the flexible rubber cylinder 2. A tension spring 7 is fitted on the sliding rod 5 between the fixing ring 4 and the baffle 6. Both ends are fixedly installed together with the fixing ring 4 and the baffle 6 respectively. There are several ways to install the baffle 6 and the tension spring 7. For example, the baffle 6 is welded to the slide rod 5, and both ends of the tension spring 7 are welded together with the fixing ring 4 and the baffle 6 respectively. The two iron wires 3 and the two slide rods 5 are arranged in a cross shape to make the flexible rubber cylinder 2 more firmly fixed. The lower part of the slide rod 5 is bent towards the side close to the flexible rubber cylinder 2. The lower end of the flexible rubber cylinder 2 is welded with a connecting plate 8, and the connecting plate 8 is bolted to the flexible rubber cylinder 2 to facilitate the replacement of the flexible rubber cylinder 2.

[0014] Working principle: When the picker is working, the tension spring 7 drives the slide bar 5 to move axially, so that the lower end of the flexible rubber cylinder 2 comes into contact with the object to be worked, thereby isolating the crushed pieces inside the flexible rubber cylinder 2 and preventing the pieces from flying. Through the design of the tension spring 7 and the slide bar 5, not only can the fragments flying when the picker is working downwards be avoided, but the fragments flying when the picker is working upwards can also be avoided.

[0015] Example 2: The difference between Example 2 and Example 1 is that the flexible rubber cylinder 2 is a multi-section folded corrugated pipe structure with a spiral steel wire skeleton embedded in the pipe wall, which maintains axial extensibility and improves radial impact resistance.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
