[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Embodiment 1
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a prestressed anchor cable tensioning device proposed by the utility model comprises an insertion tube 1 and a connecting head 2. The front of the insertion tube 1 is equipped with a connecting head 2. The insertion tube 1 provides fixing points for the connecting head 2 and the insertion hole 9 installed on its outer surface. Before using the device, the insertion tube 1 is inserted into the interior of the external slope tunnel. The connecting head 2 provides a shield for the front of the slope tunnel, and at the same time provides a fixing point for a connecting plate 3 installed on its front by bolts. The front of the connecting head 2 is equipped with a connecting plate 3 by bolts. The connecting plate 3 is installed to the front of the connecting head 2 by bolts, providing a fixing point for a first fixing ring 4 installed on its front. The front of the connecting plate 3 is equipped with a first fixing ring 4. The first fixing ring 4 is installed to the front of the connecting plate 3, providing a fixing point for a shock absorber 5 installed on its front. Eight groups of shock absorbers 5 are installed on the front of the first fixing ring 4. When the tensioning force on the cable changes, the shock absorber 5 can be moved in a variable direction. Within the dynamic range, elastic deformation occurs to absorb the impact force to prevent the cable from being broken by the hard pulling force. A second fixing ring 6 is installed at the tail end of the eight shock absorbers 5. The second fixing ring 6 is installed to the tail end of the shock absorber 5 to provide a fixing point for the connecting disk 7 installed on the front thereof. A connecting disk 7 is installed on the front of the second fixing ring 6. The connecting disk 7 is installed to the front of the second fixing ring 6 to provide a fixing point for the lead-out hole 8 opened through the outer surface thereof, and at the same time, a fixing point is provided for the signal transmitter 11 and the battery 12 installed on the outer surface thereof. A lead-out hole 8 is opened through the outer surface of the connecting disk 7. The lead-out hole 8 is opened through the outer surface of the connecting disk 7 to provide space for the lead-out of the tail end of the cable, and is moved to the outside of the lead-out hole 8 through the cable external connecting buckle to complete the fixation of the cable. A plurality of insertion holes 9 are penetrated on the back of the insertion tube 1. One end of the cable is introduced into the insertion hole 9 before using the device.
[0022] The working principle of a prestressed anchor cable tensioning device based on Example 1 is: first, insert the insertion tube 1 into the interior of the external slope tunnel, then guide one end of the cable into the interior of the insertion hole 9, and lead the cable out to the external environment, and fix it to the outer surface of the connecting plate 7 via the external fixing head of the cable to complete the fixation of the anchor cable tensioning device. When the tensioning force on the cable changes, the shock absorber 5 undergoes elastic deformation within the movable range to absorb the impact force, thereby preventing the cable from breaking due to the influence of hard tension.

When the electric energy is transmitted to the inside of the signal transmitter 11 via the pressure switch 10, the signal transmitter 11 transmits the electric signal to the inside of the external receiving component to remind the staff that the cable may be overloaded, thereby affecting the safety of the cable. Two groups of batteries 12 are installed on the front of the connecting disk 7, and the battery 12 is located on one side of the signal transmitter 11. The battery 12 is installed on the front of the connecting disk 7 to transmit electric energy to the inside of the four groups of pressure switches 10 respectively. When the pressure switch 10 is connected, the electric energy inside the battery 12 is transmitted to the inside of the signal transmitter 11.
