[0002] Grouting anchor cables (also known as hollow grouting anchor cables) are widely used in tunnel support. Existing grouting anchor cable technology is mature, consisting of a grouting core tube, with multiple steel bars wrapped around it to form the cable body. The grouting core tube has a grouting joint welded to the front end and a grouting outlet at the rear end. The cable body is equipped with a grouting stopper and a lock.

[0003] To reduce costs, the prior art generally uses metal tubes and rubber-plastic tubes to make grouting core tubes. The metal tube is relatively short and located at the front end for welding, while the rubber-plastic tube is relatively long and located at the rear end. The prior art generally uses a heating method to connect the rubber-plastic tube to the metal tube. That is, one end of the metal tube is heated, and then the rubber-plastic tube is placed over the heated end of the metal tube for connection. Although the connection principle is very simple, the prior art does not have dedicated equipment to achieve efficient mass-produced heating connection operations. Therefore, it is necessary to design a grouting core tube heating connection device that is easy to operate and can be mass-produced according to actual needs.

The material rack A3 is used to place multiple metal pipes 10, the induction heating device 4 is used to heat a single metal pipe 10, and the material rack B5 is used to place multiple rubber and plastic pipes 11. A cooling pool 6 is provided on the workbench 2, and a cooling liquid is provided in the cooling pool 6. A material rack C7 is provided at the front end of the workbench 2, and the material rack C7 is used to place multiple connected grouting core pipes 12. By designing the rack A3, induction heating equipment 4, rack B5 and cooling pool 6, it is possible to place multiple metal tubes 10 on the rack A3 and multiple rubber-plastic tubes 11 on the rack 5B for easy manual handling. The induction heating equipment 4 is used to quickly heat the ends of the metal tubes 10, and the cooling pool 6 facilitates cooling the ends of the metal tubes 10. After cooling, the rubber-plastic tubes 11 are sleeved on the heated ends of the metal tubes 10 to achieve connection, and the connected grouting core tubes 12 are placed on the rack C7 for easy centralized packaging and collection. The entire process can be completed by only one person, and the operation is relatively simple, which helps to improve work efficiency. The induction heating equipment 4 in this application belongs to the prior art and can be directly customized or purchased. Among them, the rack A3, rack B5 and rack C7 are preferably made of stainless steel.

[0027] Casters 8 are provided at the four corners of the lower end of the frame 1, so as to facilitate the movement of the position according to the site.

[0028] The frame 1 includes four legs 101 arranged in a rectangular shape, with a crossbeam 102 connecting two adjacent legs 101. The legs 101 are hollow, and a lifting rod 103 is sleeved on the upper end of each leg 101. The legs 101 are provided with positioning holes 104. The lifting rod 103 is provided with a plurality of vertically spaced adjustment holes 105, one of which is aligned with the positioning hole 104 and is provided with a positioning pin 106. The work table 2 is provided on the upper end of the lifting rod 103. The height of the work table 2 can be adjusted to meet the needs of operators of different heights.

[0029] The rack A3 includes a plurality of supports A301 spaced laterally apart, each support A301 including two vertically spaced columns A302, a curved steel bar A303 disposed between the two columns A302, and the metal tube 10 disposed on the curved steel bar A303, making it easy to place and take the metal tube 10.

[0030] The material rack B5 includes an arc-shaped steel bar B501, and the lower end of the arc-shaped steel bar B501 is installed on the workbench 2 through a plurality of columns B502, so as to facilitate the placement of the rubber and plastic pipe 11 and the taking out of the rubber and plastic pipe 11.

The pulley frame 901 is provided with a pulley 902. One end of the rope 903 is placed on the workbench 2, and the other end passes through the pulley 902 and is provided with a counterweight 904. The winding mechanism 9 is mainly used to wrap the ends of the rubber and plastic tubes 11 with the rope (mainly to restrain them, not to tie them up), making it easier to place multiple rubber and plastic tubes 11.

[0032] The rack C7 includes a U-shaped plate 701, which is arranged at the front end of the workbench 2. It is convenient for storing the connected grouting core tubes and is also conducive to centralized collection.

[0033] Instructions for use of a grouting core pipe heating connection device in this application:

[0034] In actual use, a chair is required for the operator to sit on and operate. In addition, the induction heating equipment 4 is a prior art and can be directly customized or purchased (for example, the GY-25A high-frequency induction heating equipment produced by Dongguan Wanjiang Guangyuan Frequency Conversion Electronic Equipment Factory can be used). At the same time, the induction heating equipment 4 needs to be equipped with a distribution box 13, a foot switch 14, an induction heating coil 15, a circulating cooling water tank 16, and a circulating cooling pump.

[0035] During production, first place multiple metal tubes 10 on the rack A3, and place multiple rubber and plastic tubes 11 on the rack B5. At the same time, use rope 903 to wrap the ends of the multiple rubber and plastic tubes 11 one or two times, and tighten and constrain them through counterweight blocks 904 to power the induction heating equipment 4. The operator then sits on a chair, wearing safety gloves (to prevent burns during operation). He then takes a metal tube 10 with his right hand, places one end of the tube 10 inside the induction heating coil 15, holds the other end in his hand, and simultaneously touches the foot switch 14 with his foot. The induction heating device 4 begins heating the tube 10 (usually within 2-5 seconds, heating is completed, as evidenced by the reddening of the heated end of the tube 10). After heating is complete, he releases the foot switch 14 to stop heating. He then removes the tube 10 and places the heated end into the cooling tank 6 to cool it down (generally, the tube 10 is inserted into the cooling tank 6 quickly 1-3 times). He then removes a rubber-plastic tube 11 with his left hand and quickly inserts the heated end of the tube 10 into the tube 11 (although the tube 10 has been cooled, the temperature is still high, allowing the tube 10 to easily insert into the tube 11). This completes the connection, and the connected grouting core tube 12 is then placed on the rack C7. Heating and connection are then continued according to the above steps to achieve mass production of the grouting core tube 12.

[0036] The above specific implementation methods cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or transformation made to the implementation methods of the present utility model falls within the protection scope of the present utility model.

[0037] Anything not described in detail in the present invention is well known to those skilled in the art.
