[0031] 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.

Based on the embodiments of 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.

[0032] Example 1

[0033] See also Figure 1-Figure 7 As shown, the utility model is a comprehensive detection auxiliary device for the thickness of the thermal insulation layer, comprising an installation chamber 1, and a controller for controlling other electrical components on the installation chamber 1 is arranged outside the installation chamber 1;

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, both ends of one side of the installation bin 1 are installed with rope guide plates 6, both ends of the side of the installation bin 1 away from the rope guide plate 6 are provided with reciprocating screws 7, and the end of the reciprocating screw 7 close to the rope guide plate 6 is provided with a first gear 8, the outer side of the reciprocating screw 7 is sleeved with a movable plate 9, and one side of a group of movable plates 9 close to the rope guide plate 6 is provided with two groups of cutting ropes 10, and the other end of the cutting rope 10 is connected to the other group of movable plates 9, and the cutting rope 10 passes through the rope guide plate 6. The cutting rope 10 can be made of existing composite steel wire and other materials that can be used for cutting, and the part of the cutting rope 10 exposed outside the rope guide plate 6 forms two upper and lower semicircular states;

[0035] like Figure 1 As shown, a handle 2 is installed on the side of the installation compartment 1 away from the rope guide plate 6, and the outer wall of the handle 2 is provided with anti-slip grooves to facilitate the staff to lift and use the device;

[0036] like Figure 2 As shown, the top and bottom of the installation chamber 1 near the rope guide plate 6 are both installed with a limiting plate 5, and the side cross-section of the limiting plate 5 is arc-shaped. The limiting plate 5 is not connected to the cutting rope 10. The limiting plate 5 is used to limit the cutting rope 10 when the rope guide plate 6 and the cutting rope 10 are inserted into the gap between the sample and the wall, ensuring that the cutting rope 10 can be pressed against the bottom of the gap;

[0037] like Figure 5 As shown, the movable plate 9 is threadedly connected to the reciprocating screw 7, and the movable plate 9 and the mounting bin 1 form a sliding structure. The initial positions of the two sets of movable plates 9 are different, one set is located at the beginning of the stroke, and the other set is located at the end of the stroke. When the two sets of reciprocating screws 7 rotate at the same time, when one set of movable plates 9 pulls one end of the two sets of cutting ropes 10, the other set of movable plates 9 releases the other end of the two sets of cutting ropes 10, so that the two sets of cutting ropes 10 can be continuously twisted;

[0038] like Figure 5 and Figure 6As shown, a fixing plate 11 is installed at the middle position of both ends of the bottom of the installation bin 1, and an elastic mechanism for squeezing the cutting rope 10 is arranged on the fixing plate 11, and the elastic mechanism includes an extrusion member 12, and the extrusion member 12 runs through one end of the fixing plate 11, and a spring 13 is connected between the extrusion member 12 and the fixing plate 11, and a guide roller assembly 14 is installed at one end of the extrusion member 12 close to the cutting rope 10, and the cross-sectional shape of the extrusion member 12 is "T"-shaped, and the extrusion member 12 and the fixing plate 11 form a sliding structure, so that when the two groups of extrusion members 12 move outward at the same time, the part of the cutting rope 10 located inside the installation bin 1 can be bent, so that the cutting part exposed outside the rope guide plate 6 is continuously tightened and contracted, so as to cooperate to complete the continuous cutting task;

[0039] like Figure 5 As shown, a driving mechanism for driving the reciprocating screw 7 to rotate is provided on the installation bin 1, and the driving mechanism includes a servo motor 15, which is installed on a side of the installation bin 1 close to the rope guide plate 6, and the output end of the servo motor 15 is connected to a screw body 16, and a trapezoidal block 17 is sleeved on the outer side of one end of the screw body 16 close to the rope guide plate 6, and a second gear 18 is installed on the outer side of the end of the screw body 16 away from the rope guide plate 6, and the trapezoidal block 17 and the installation bin 1 form a sliding structure, and the trapezoidal block 17 and the screw body 16 are threadedly connected, the central axis of the second gear 18 is parallel to the central axis of the first gear 8, and the second gear 18 and the first gear 8 are meshingly connected, so that when the servo motor 15 drives the screw body 16 to rotate forward, the trapezoidal block 17 can move in the direction close to the rope guide plate 6, thereby cooperating with the elastic mechanism to extrude and bend the cutting rope 10, and at the same time can drive the two groups of reciprocating screws 7 to rotate together;

[0040] Example 2

[0041] like Figure 1 As shown, a hydraulic cylinder 3 is installed at one end of the mounting bin 1 close to the rope guide plate 6, and the output end of the hydraulic cylinder 3 is connected to a top plate 4, so that during use, the staff can press the top plate 4 against the wall to ensure that the device remains vertical to the wall. At the same time, for samples of different lengths, the position of the top plate 4 relative to the mounting bin 1 can be adjusted by the hydraulic cylinder 3, so that when the top plate 4 is in contact with the wall, the cutting part of the cutting rope 10 can enter the end where the sample is connected to the wall.

[0042] Working principle of the utility model: the device is powered by an external power supply or a battery. When in use, the coring instrument is used to try the coring task on the wall, so that a circular gap is formed on the wall. Then the device is lifted by the handle 2, and the limiting plate 5 and the rope guide plate 6 are inserted into the above gap until the cutting rope 10 exposed outside the rope guide plate 6 enters the bottom of the gap. At this time, the hydraulic cylinder 3 is controlled to drive the top plate 4 to move toward the wall until the top plate 4 is fully fitted with the wall, thereby ensuring that the device is vertical to the wall.

[0043] After the above preparation operation is completed, the servo motor 15 is controlled by the controller to drive the screw body 16 to rotate forward, and the second gear 18 is meshed with the first gear 8, so that the two groups of reciprocating screws 7 rotate at the same time. The movable plate 9 is threadedly connected to the reciprocating screw 7, so that the two groups of movable plates 9 can continuously reciprocate and move horizontally at the same time. Since one group of the two groups of movable plates 9 is located at the beginning of the stroke and the other group is located at the end of the stroke in the initial state, the two groups of movable plates 9 always maintain opposite movement directions at this time. When one group of movable plates 9 pulls one end of the two groups of cutting ropes 10, the other group of movable plates 9 releases the other end of the two groups of cutting ropes 10, so that the two groups of cutting ropes 10 can be continuously rubbed, and at the same time, The upper and lower parts of the end of the product are used for cutting, and the trapezoidal block 17 is further connected with the screw body 16 through a thread, so that the trapezoidal block 17 can move toward the direction close to the extrusion member 12, thereby squeezing the two groups of extrusion members 12 away from the middle. The extrusion member 12 further pushes the cutting rope 10 away from the middle through the guide roller assembly 14, so that the cutting rope 10 exposed outside the two groups of rope guide plates 6 is continuously tightened, thereby cooperating to complete the continuous cutting task until the part is tightened to a horizontal state, completing the cutting task, and removing the sample from the wall. Subsequently, the servo motor 15 is controlled to drive the screw body 16 to reverse the above-mentioned stroke to reset the device for the next application.

[0044] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
