Description

Technical Field

[0001] The utility model relates to auxiliary equipment for pouring inclined cable anchors, in particular to a vibration pump installation tool for pouring anchors. Background Art

[0002] like Figure 1 As shown, in the prior art, the installation tool for the vibration pump for anchoring includes: a first hoop ring, a second hoop ring, two bolts and two nuts. The first hoop ring and the second hoop ring surround the outside of the anchor cup. The steel strand of the inclined cable is inserted into the anchor cup. An anchor plate is installed in the anchor cup. The anchor plate separates the originally closed steel strands. After the steel strands are separated, a pouring space is formed between the inner wall of the anchor cup. The pouring space needs to be poured with material. When pouring the material, a vibration pump needs to be used to make the pouring material evenly distributed in the pouring space, reduce the generation of bubbles, and ensure the anchoring strength. A first threaded hole is opened at one end of the anchor cup away from the middle of the steel strand. The first threaded hole is used to connect to an external anchoring structure. The ends of the first hoop ring and the second hoop ring are penetrated by bolts, and the bolts are threadedly connected to nuts. The nuts and the large ends of the bolts cooperate to clamp the ends of the first hoop ring and the second hoop ring to maintain the clamped state. A vibration pump is installed on the first hoop ring and / or the second hoop ring.

[0003] Although the above-mentioned vibration pump installation tool for anchor grouting can realize the installation of the vibration pump outside the anchor cup, the vibration pump installation tool for anchor grouting still has the following disadvantages: the outer wall of the anchor cup is smooth, and the friction between the first clamping ring, the second clamping ring and the anchor cup is small. When the vibration pump is working, the vibration pump and the entire vibration pump installation tool for anchor grouting will move randomly on the anchor cup, resulting in the wrong vibration position, which reduces the vibration effect.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0024] like Figures 2 to 6 As shown, the utility model discloses a vibration pump installation tool for anchor grouting, comprising: a first hoop ring 11, a second hoop ring 12, a bolt 13, a nut 14, a connecting seat 2 and a positioning device 3; the first hoop ring 11 and the second hoop ring 12 are surrounded by the anchor cup 16, the ends of the first hoop ring 11 and the second hoop ring 12 are passed through by the bolt 13, the bolt 13 is threadedly connected to the nut 14, and the nut 14 cooperates with the large end of the bolt 13 to clamp the ends of the first hoop ring 11 and the second hoop ring 12; the side walls of the first hoop ring 11 and the second hoop ring 12 are both protruding to form a connecting seat 2, and the connecting seat 2 is installed with a vibration pump; a positioning device 3 is installed at the connection between the nut 14 and the bolt 13, and the positioning device 3 is used to limit the movement of the first hoop ring 11 and the second hoop ring 12 in the axial direction of the anchor cup 16.

[0025] The positioning device 3 includes: a positioning arm 31 and a mounting seat 32. The mounting seat 32 covers the ends of the first hoop ring 11 and the second hoop ring 12. The positioning arm 31 that can move in the radial direction of the anchor cup 16 is installed on the mounting seat 32. The positioning arm 31 is provided with a first positioning hole for the bolt 13 to pass through. The two ends of the positioning arm 31 are used to hook the end surface of the anchor cup 16 after the bolt 13 passes through the first positioning hole. When the mounting seat 32 is stuck outside the first hoop ring 11 and the second hoop ring 12, the positioning arm 31 is in a state of being away from the anchor cup 16, so as to avoid the two ends of the positioning arm 31 being stuck on the end surface of the anchor cup 16, which causes the mounting seat 32 to be stuck outside the first hoop ring 11 and the second hoop ring 12. Difficulty in operation. After the mounting seat 32 is installed, move the positioning arm 31 so that the two ends of the positioning arm 31 are respectively clamped on the end surfaces of the anchor cup 16. Finally, pass the bolt 13 through the mounting seat 32, the positioning arm 31, the first clamping ring 11 and the second clamping ring 12, and thread the nut 14 on the bolt 13. Then, the positioning arm 31 can be positioned to hook the anchor cup 16, and the first clamping ring 11 and the second clamping ring 12 can be positioned at the same time.

[0026] An anti-rotation arm 33 is installed on the positioning arm 31. The anti-rotation arm 33 can move relative to the installation arm in the axial direction of the anchor cup 16. The anti-rotation arm 33 is used to extend into the first threaded hole 17 of the anchor cup 16. Due to the vibration of the vibration pump, the first hoop ring 11 and the second hoop ring 12 may also rotate outside the anchor cup 16. Therefore, it is designed that the anti-rotation arm 33 extends into the first threaded hole 17 after installation to limit the rotation of the vibration pump.

[0027] A second positioning hole is provided on the anti-rotation arm 33, and the second positioning hole is used for the bolt 13 to pass through when the anti-rotation arm 33 extends into the first threaded hole 17. The design of the second positioning hole enables the bolt 13 to pass through the anti-rotation arm 33 when passing through the positioning arm 31, and the anti-rotation arm 33 is positioned to extend into the first threaded hole 17. Both the positioning arm 31 and the anti-rotation arm 33 are positioned by the barrel bolt 13 and the nut 14, which simplifies the structure, makes the cost lower, and is more convenient to use.

[0028] The mounting seat 32 is provided with a third positioning hole for the bolt 13 to pass through, and a spring 34 is installed inside. One end of the spring 34 is connected to the inner wall of the mounting seat 32, and the other end of the spring 34 is connected to the positioning arm 31. Under the elastic force of the spring 34, the first positioning hole on the positioning arm 31 deviates from the third positioning hole. The third positioning hole is for the bolt 13 to pass through the mounting seat 32. When the mounting seat 32 is clamped on the ends of the first hoop ring 11 and the second hoop ring 12, the elastic force of the spring 34 makes the positioning arm 31 on the mounting seat 32 away from the anchor cup 16, so that the mounting seat 32 is conveniently clamped on the ends of the first hoop ring 11 and the second hoop ring 12.

[0029] A second threaded hole 20 is provided on the connection base 2, and the second threaded hole 20 is used to install the vibration pump. The second threaded hole 20 realizes the installation of the vibration pump.

[0030] The second threaded hole 20 is formed at the end of the connection seat 2, and a chamfered surface 21 is formed at the end of the connection seat 2, and the chamfered surface 21 is located at the corner of the end of the connection seat 2 close to the side wall of the first clamp ring 11 or the second clamp ring 12. The design of the chamfered surface 21 increases the distance between the second threaded hole 20 and the side wall of the anchor cup 16, which is convenient for installing the vibration pump.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
