Description

Technical Field

[0001] The utility model belongs to the technical field of anchor rod installation and relates to an auxiliary propulsion device for supporting anchor rods. Background Art

[0002] Double-layer sprayed anchor nets are commonly used in engineering support for mining, tunnel infrastructure, water conservancy projects, etc. The common anchor rod specification is Φ18mm threaded pad anchor rod. Affected by the working environment and engineering conditions, the use of large-scale anchor-in-one equipment is limited. Handheld drilling and manual anchoring are often used. After drilling and grouting, a tool such as a sledgehammer is needed to quickly smash the anchor rod into the eye so that it can play a supporting and bearing role after solidification. This operation method consumes a lot of physical energy and often requires personnel to stand at high altitudes. Improper operation can easily cause safety accidents such as falls and tool slippage. Utility Model Content

[0006] Furthermore, the connecting rod and the anchor rod clamping tube are coaxially arranged.

[0007] Furthermore, a first limit plate and a second limit plate are fixed on the connecting rod, the first limit plate is located at the inner end of the connecting rod, and the second limit plate is located outside the shell.

[0008] Furthermore, the rotating shaft and the guide tube are arranged perpendicular to each other.

[0009] Furthermore, the connecting rod and the rotating shaft are arranged perpendicular to each other.

[0010] Furthermore, a handle is provided on the shell.

[0011] The beneficial effects of the present utility model are as follows: A rotatable striker is arranged inside the housing. By striking the connecting rod with the striker, external force is transmitted to the anchor rod, pushing the anchor rod to move into the hole, and completing the insertion of the anchor rod. During operation, the operator only needs to hold the housing by the handle and press it, which is time-saving, labor-saving, convenient and fast; the structure is simple and the manufacturing cost is low.

[0015] The following makes a detailed description of the present utility model in conjunction with the drawings:

[0016] Such as Figure 1 And 2As shown, a supporting anchor auxiliary propulsion device comprises a shell 1, which is made of stainless steel. A guide tube 2 is fixed in the shell 1, one end of the guide tube 2 passes through the shell 1, a connecting rod 3 is arranged in the guide tube 2, the length of the connecting rod 3 is greater than the length of the guide tube 2, the connecting rod 3 can move back and forth in the guide tube 2 along the length direction of the guide tube 2, an end of the connecting rod 3 away from the shell is provided with an anchor clamping tube 4 coaxially arranged with the connecting rod, the anchor clamping tube 4 can be sleeved on the outer end of the anchor, the end of the anchor clamping tube 4 can abut on the nut of the anchor, an external force is applied to the nut of the anchor through the anchor clamping tube 4, and then the anchor is pushed to move, a rotating shaft 5 is arranged perpendicular to the guide tube 2 in the shell 1, one end of the rotating shaft 5 passes through the shell 1, the outer end of the rotating shaft 5 is connected to a motor 6 for driving the rotating shaft 5 to rotate, the motor 6 is installed on the shell 1, and the rotating shaft 5 is connected to The rotating shaft is a connecting rod 7 which is arranged perpendicular to each other. The connecting rod 7 is located in the shell 1 and can rotate with the rotating shaft 5. The end of the connecting rod 7 away from the rotating shaft 5 is provided with a hammer 8 corresponding to the inner end of the connecting rod 3. The hammer 8 is driven by the connecting rod 7 to rotate and can hit the inner end of the connecting rod 3. The connecting rod 3 moves toward the outer end of the guide tube 2, so that an external force is applied to the anchor rod through the anchor rod clamping tube 4 to quickly insert the anchor rod into the eye. In order to prevent the connecting rod 3 from escaping from the guide tube 2, a first limit plate 9 and a second limit plate 10 are fixed on the connecting rod 3. The first limit plate 9 is located at the inner end of the connecting rod 3, and the second limit plate 10 is located outside the shell 1. The first limit plate 9 can prevent the connecting rod 3 from escaping from the outer end of the guide tube 2 when it moves toward the outer end of the guide tube 2, and the second limit plate 10 can prevent the connecting rod 3 from moving too far when it moves toward the inner end of the guide tube 2, resulting in the hammer 8 being unable to hit the inner end of the connecting rod 3.

[0017] For ease of use, a handle 11 is provided on the housing 1 , and an operator can hold the handle 11 for operation.

[0018] The usage of the utility model is as follows:

[0019] When it is necessary to insert the anchor rod into the eye after grouting, first, the anchor rod clamping tube 4 is sleeved on the outer end of the anchor rod, and the end of the anchor rod clamping tube 4 is made to abut against the nut of the anchor rod to complete the installation of the device. The operator holds the handle 11 and pushes the shell 1 forward so that the outer end of the guide tube 2 abuts against the second limit plate 10. Then the motor 6 can be started to drive the rotating shaft 5 to rotate, and the rotating shaft 5 drives the connecting rod 7 and the hammer 8 to rotate. The inner end of the connecting rod 3 is continuously struck by the hammer 8. The external force applied by the hammer 8 to the connecting rod 3 is transmitted to the anchor rod through the anchor rod clamping tube 4 to insert the anchor rod into the eye. During this process, the operator holds the handle and continuously pushes the shell 1 in the direction of anchor rod insertion until the anchor rod is completely inserted into the eye and stops. After completion, the anchor rod clamping tube 4 can be taken out from the anchor rod. The whole process is convenient and quick, and only one operator is needed to complete it, saving time and effort.
