Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 3 , the present invention provides a technical solution for an anchor rod pulling device for road maintenance:

[0021] Embodiment 1:

[0022] According to Figure 1 and Figure 3 shown, an anchor rod pulling device for road maintenance includes a portable box 1. An installation plate 18 is provided inside the portable box 1. A pulling device main body 2 is installed at the top end of the installation plate 18. A high-pressure oil pipe 3 is installed in the middle of the pulling device main body 2. One end of the high-pressure oil pipe 3 far away from the pulling device main body 2 is installed with a hydraulic cylinder 4. An installation ring is fixedly connected to the middle of the outer wall of the hydraulic cylinder 4. Columnar boxes 6 are fixedly connected to both side walls of the installation ring. A rotating rod 16 is rotatably connected inside the columnar box 6. An elastic band 7 is wound around the outer wall of the rotating rod 16. One end of the elastic band 7 far away from the hydraulic cylinder 4 is fixedly connected with a rubber socket 8. The rubber socket 8 can be stably sleeved on other anchor rods to form a suspension support and protect the hydraulic cylinder 4.

[0023] The top end of the portable box 1 is snap-connected with a box cover 13. Arc-shaped grooves 12 are opened on one side of the top end of the portable box 1 and one side of the bottom end of the box cover 13. The middle of the high-pressure oil pipe 3 penetrates through the two arc-shaped grooves 12. A coil spring 17 is sleeved at the bottom of the rotating rod 16. One end of the coil spring 17 is fixedly connected to the outer wall of the rotating rod 16, and the other end of the coil spring 17 is fixedly connected to the inner wall of the columnar box 6. The coil spring 17 can keep the elastic band 7 can be pulled out. When the elastic band 7 is used up, with the help of the resilience of the coil spring 17, the elastic band 7 can be wound back. A strip-shaped groove is opened on the outer wall of the columnar box 6, and the middle of the elastic band 7 penetrates through the strip-shaped groove.

[0024] During specific use, for a bolt pulling device for road maintenance of the present utility model, the operator can install the pulling device main body 2 inside the portable box 1 by means of the mounting plate 18, install the box cover 13 on the top of the portable box 1, and snap the hydraulic cylinder 4 inside the arc-shaped clamp 9, then the pulling device can be carried. When it is necessary to pull the bolt, the box cover 13 can be opened, the hydraulic cylinder 4 can be taken out of the arc-shaped clamp 9 and installed on the bolt. Pull the rubber sleeves 8 on both sides of the hydraulic cylinder 4, so that the elastic bands 7 on both sides are pulled out. The two rubber sleeves 8 are respectively sleeved on two adjacent bolts, and the hydraulic cylinder 4 is lifted by means of the two taut elastic bands 7, so as to avoid the hydraulic cylinder 4 falling after the bolt breaks during the pulling process, and provide hanging protection for the hydraulic cylinder 4. After the pulling is completed, the rubber sleeves 8 are removed. Under the winding drive of the coil spring 17, the two elastic bands 7 will be retracted into the cylindrical box 6. When cooperating with another staff member, the hydraulic cylinder 4 can also be lifted by another staff member holding the grip rod 5, further avoiding the risk of the hydraulic cylinder 4 falling after the bolt is pulled off.

[0025] Embodiment 2:

[0026] On the basis of Embodiment 1, as Figure 1 and Figure 2 shown, a pressure rod 10 is installed in the middle of the top of the pulling device main body 2. A foot sleeve 14 is sleeved on one end of the pressure rod 10. Two cross plates are fixedly connected to the top of the foot sleeve 14. One foot can step on the two cross plates, and the front part of the foot can be inserted into the elastic sleeve belt 15. An elastic sleeve belt 15 is fixedly connected to the top of one of the cross plates. A grip sleeve 11 is placed inside the portable box 1. A grip rod 5 is fixedly connected to the side wall of the hydraulic cylinder 4. An arc-shaped clamp 9 is fixedly connected to the side wall of the portable box 1. The size of the grip sleeve 11 matches the size of the pressure rod 10. When two people cooperate, the grip sleeve 11 can be changed to the pressure rod 10, and the operation can be carried out by holding the grip sleeve 11 with the hand.

[0027] During specific use, for a bolt pulling device for road maintenance of the present utility model, during the process of pulling the bolt, if the operator is two people cooperating, the operator can sleeve the grip sleeve 11 on the pressure rod 10, so that the hand holds the grip sleeve 11 and drives the pressure rod 10 to press up and down for pulling. When the operator is operating alone, when there is no other bolt nearby for hanging when pulling the bolt, the grip sleeve 11 can be replaced with the foot sleeve 14. In this way, the operator can hold the grip rod 5 with one hand and pass one foot between the elastic sleeve belts 15 of the foot sleeve 14, and operate the pressure rod 10 by means of the lifting and kicking of the foot. In this way, a single person can also carry out the bolt pulling operation and can maintain the stability of the hydraulic cylinder 4.
