[0003] In the related art, when conducting on-site acceptance of project quality, quality engineers need to carry various instruments to the project site for measurement and acceptance. During random spot checks, quality engineers need to measure in different buildings, which makes it inconvenient for engineers to carry instruments and time-consuming and laborious. Summary of the Invention

[0004] In order to enable one instrument to measure multi-item wall data and reduce the amount of instruments carried by operators, this application provides a device for actual measurement and acceptance of engineering supervision quality.

[0005] A device for actual measurement and acceptance of engineering supervision quality provided by this application adopts the following technical solution:

[0006] A device for actual measurement and acceptance of engineering supervision quality includes a box body and a number of support seats arranged on the box body. A level meter is arranged on the box body. A rebound rod for measuring concrete strength is slidably inserted through the box body. A detection spring is fixedly connected to the rebound rod. The end of the detection spring away from the rebound rod is fixedly connected to the inner side wall of the box body. An indicating rod for detecting the rebound degree of the rebound rod is arranged on the box body. A detection rod for measuring the wall inclination is arranged on the box body. A reset assembly for driving the movement of the rebound rod is arranged on the box body. A fixing assembly for controlling the position of the rebound rod is arranged on the box body.

[0007] By adopting the above technical solution, the operator presses the rebound rod to compress the detection spring, the operator uses the fixing assembly to fix the position of the rebound rod, and then the operator releases the rebound rod. The rebound rod impacts the concrete under the action of the detection spring and rebounds a certain distance. The operator can observe the rebound distance through the indicating rod and calculate the rebound rate. The reset assembly drives the rebound rod back to the initial position. The operator uses the level meter to ensure that the box body is in a horizontal state, and then the operator uses the detection rod to measure the wall inclination, realizing that one instrument can measure multi-item wall data at the same time and reducing the amount of instruments carried by operators during the actual measurement of building quality.

[0008] Preferably, the reset assembly includes a reset rod and a first clamping block. The reset rod is slidably inserted into the box body. A first sliding groove for slidably cooperating with the reset rod is formed in the box body. The first clamping block is fixedly connected to the rebounding rod. The first clamping block is clamped with the reset rod. The first clamping block and the reset rod are both provided with inclined surfaces. A first driving assembly for driving the reset rod to move is arranged in the box body.

[0009] By adopting the above technical solution, when an operator measures the rebound rate of a wall, the first driving assembly drives the reset rod to move. The reset rod moves to push the first clamping block to move. The movement of the first clamping block causes the rebounding rod to move and compress the detection spring. Then the fixing assembly fixes the rebounding rod. The operator then uses the fixing assembly to release the rebounding rod to achieve the purpose of measuring the concrete rebound rate.

[0010] Preferably, the first driving assembly includes a first rack, a linkage gear and a protection cylinder arranged on the reset rod. The end of the first rack away from the reset rod is slidably connected to the box body. The protection cylinder is slidably inserted into the box body. The linkage gear is rotatably installed on the inner side wall of the box body close to the protection cylinder. A second rack is fixedly connected to the protection cylinder. The first rack and the second rack are both engaged with the linkage gear. A control assembly for controlling the position of the reset rod is arranged in the box body.

[0011] By adopting the above technical solution, when an operator measures the rebound rate of the outer layer of a wall, the operator pulls the protection cylinder to make the protection cylinder close to the wall. The protection cylinder can prevent the coating powder from being scattered into the air when the rebounding rod impacts the coating. When the operator pulls the protection cylinder to move towards the measurement point, the protection cylinder causes the second rack to move. The movement of the second rack causes the linkage gear to rotate. The rotation of the linkage gear causes the first rack to move. The movement of the first rack causes the reset rod to move. When the reset rod moves, it pushes the first clamping block to move. The movement of the first clamping block causes the rebounding rod to move. The rebounding rod moves to compress the detection spring. The rebounding rod compresses the detection spring and is fixed by the fixing assembly at the same time and stops moving.

[0012] Preferably, the fixing assembly includes a pull rod and a second clamping block. The pull rod is slidably inserted into the box body. The pull rod penetrates into the box body. The second clamping block is fixedly connected to the end of the rebounding rod close to the pull rod. The second clamping block is clamped with the pull rod. The ends of the pull rod and the second clamping block close to each other are both provided with inclined surfaces. A first return spring is fixedly connected to the end of the pull rod located inside the box body. The end of the first return spring away from the pull rod is fixedly connected to the inner side wall of the box body.

[0013] By adopting the above technical solution, the operator pulls the protection cylinder, the protection cylinder moves the second rack, the movement of the second rack causes the linkage gear to rotate, the rotation of the linkage gear causes the first rack to move, the movement of the first rack causes the reset rod to move, and when the reset rod moves, it pushes the first block to move. The movement of the first block causes the return rod to move. During the process of the return rod moving and compressing the detection spring, the second block abuts against the pull rod, the second block pushes the pull rod to compress the first return spring, and then the second block is latched with the pull rod to limit the position of the return rod. At the same time, the control component drives the reset rod to move the reset rod away from the first block. The operator pulls the pull rod, and the movement of the pull rod causes the pull rod to be disengaged from the second block. At this time, the return rod impacts the wall under the action of the detection spring.

[0014] Preferably, the control component includes a push rod and a linkage rod. The push rod slidably penetrates through the box body. A long groove for slidably cooperating with the push rod is formed on the box body. A pressing spring is fixedly connected to the push rod. The end of the pressing spring away from the push rod is fixedly connected to the inner side wall of the long groove. The linkage rod is fixedly connected to the reset rod. The linkage rod abuts against the end of the push rod penetrating into the box body. An inclined surface is provided at the end of the linkage rod and the push rod close to each other. A slot for plugging and cooperating with the push rod is formed on the linkage rod. A second return spring is fixedly connected to the end of the reset rod close to the first rack. The end of the second return spring away from the reset rod is fixedly connected to the first rack. A limiting rod is slidably penetrated through the end of the reset rod close to the second return spring. The limiting rod is fixedly connected to the first rack.

[0015] By adopting the above technical solution, after the operator pulls the protection cylinder to move the return rod and the movement of the return rod causes the second block to be latched with the pull rod, the operator continues to pull the protection cylinder to make the return rod continue to move. At this time, the linkage rod abuts against the push rod. Under the action of the inclined surfaces on the linkage rod and the push rod, the push rod pushes the linkage rod to move. The movement of the linkage rod causes the reset rod to move and compress the first return spring. The movement of the reset rod causes the reset rod to move away from the first block. The reset rod moving away from the first block causes the reset rod to be disengaged from the first block. At the same time, the push rod is inserted into the slot. When the operator pulls the pull rod to release the return rod, the return rod will not be restricted by the first block and the reset rod. After the operator releases the return rod to measure the wall rebound rate, the operator pushes the push rod to make the push rod move in the long groove and compress the pressing spring. The push rod moves away from the slot. At this time, the operator can move the protection cylinder to return it to the initial position. After the protection cylinder returns to the initial position, the first rack and the reset rod both return to the initial position, and the first block is latched with the reset rod again.

[0016] Preferably, a measuring rod is slidably mounted on the end of the box body close to the detection rod. A scale is provided on the end of the measuring rod away from the box body. A second driving assembly for driving the detection rod to rotate is provided on the box body.

[0017] By adopting the above technical solution, after the rebound rod measures the rebound rate of the wall coating, the operator uses a level to adjust the box body to be horizontal. The rebound rod will leave a small groove on the coating. The operator pulls the measuring rod and inserts it into the groove. The operator uses the scale on the measuring rod to observe the coating thickness. At the same time, the second driving assembly drives the detection rod to rotate so that the detection rod is vertical and closely adheres to the wall. The operator observes whether an angle is formed between the detection rod and the wall to judge the inclination degree of the wall.

[0018] Preferably, the second driving assembly includes a third rack and a control gear. The third rack is fixedly connected to the side wall of the measuring rod close to the detection rod. The control gear is fixedly mounted on the detection rod. The third rack and the control gear are meshed with each other. A limit block is fixedly connected to the third rack. A limit groove for inserting the limit block is provided on the detection rod.

[0019] By adopting the above technical solution, the operator moves the box body so that the measuring rod is inserted into the groove. The operator continues to move the box body so that the measuring rod moves. The movement of the measuring rod causes the third rack to move. The movement of the third rack causes the control gear to rotate. The rotation of the control gear causes the detection rod to rotate. The detection rod rotates and fits with the wall. The setting of the limit block and the limit groove can limit the rotation angle of the detection rod and ensure the accuracy of the detection.

[0020] Preferably, a support rod is slidably inserted into the support seat. A plurality of fixing screws are threadedly connected to the support seat. The fixing screws penetrate into the support seat and abut against the support rod.

[0021] By adopting the above technical solution, the operator rotates the fixing screw. The operator moves the support rod to slide in the support seat and then rotates the fixing screw to fix the position of the support rod, which is convenient for the operator to adjust the height of the device and further convenient for the operator to control the detection height.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The operator presses the rebound rod to compress the detection spring, fixes the position of the rebound rod using the fixing component, then releases the rebound rod. The rebound rod impacts the concrete under the action of the detection spring and rebounds a certain distance. The operator can observe the rebound distance through the indicating rod and calculate the rebound rate. The reset component drives the rebound rod back to the initial position. The operator uses a level gauge to ensure that the box body is in a horizontal state, and then uses the detection rod to measure the wall inclination, realizing the measurement of multiple wall data with one instrument and reducing the amount of instruments carried by the operator during the actual measurement of building quality;

[0024] 2. When the operator pulls the protective cylinder to move the rebound rod, after the rebound rod moves and the second block engages with the pull rod, the operator continues to pull the protective cylinder to make the rebound rod move further. At this time, the linkage rod abuts against the push rod. Under the action of the inclined surfaces on the linkage rod and the push rod, the push rod drives the linkage rod to move. The movement of the linkage rod makes the reset rod move to compress the first return spring. The movement of the reset rod makes the reset rod move away from the first block. The reset rod moving away from the first block causes the reset rod to disengage from the first block. At the same time, the push rod is inserted into the slot. When the operator pulls the pull rod to release the rebound rod, the rebound rod will not be restricted in movement due to the first block and the reset rod. After the operator releases the rebound rod to measure the wall rebound rate, the operator pushes the push rod to make the push rod move in the long slot and compress the pressing spring. The push rod moves away from the slot. At this time, the operator can move the protective cylinder to make the protective cylinder return to the initial position. After the protective cylinder returns to the initial position, the first rack and the reset rod both return to the initial position, and the first block re-engages with the reset rod;

[0025] 3. After the rebound rod measures the rebound rate of the wall coating, the operator uses a level gauge to adjust the box body to be horizontal. The rebound rod will leave a small groove on the coating. The operator pulls the measuring rod and inserts it into the groove, and uses the scale on the measuring rod to observe the coating thickness. At the same time, the second driving component drives the detection rod to rotate so that the detection rod is vertical and closely adheres to the wall. The operator observes whether an angle is formed between the detection rod and the wall to judge the wall inclination. Description of the Drawings

[0043] Refer to Figure 4, a control component 4 is arranged inside the box body 1. The control component 4 includes a push rod 41 and a linkage rod 42. The push rod 41 is slidably connected to the inner side wall of the box body 1 close to the detection spring 14. The push rod 41 is horizontally arranged.

The linkage rod 42 abuts against the end of the push rod 41 away from the inner side wall of the box body 1. Bevels are arranged at the ends of the linkage rod 42 and the push rod 41 close to each other. A slot 412 for plugging and matching with the push rod 41 is arranged at the end of the linkage rod 42 close to the push rod 41.

[0044] The implementation principle of the engineering supervision quality acceptance actual measurement device in the embodiment of the present application is as follows: The operator first uses the level 12 to detect whether the box body 1 is in a horizontal position. The operator rotates the fixing screw 55 to control the length of the support rod 54 extending out of the support base 11 to ensure that the box body 1 is in a horizontal state, and at the same time, a certain space is reserved between the box body 1 and the wall.

[0045] The operator pulls the protection cylinder 25. The protection cylinder 25 makes the second rack 26 move. The movement of the second rack 26 makes the linkage gear 24 rotate. The rotation of the linkage gear 24 makes the first rack 23 move. The movement of the first rack 23 makes the reset rod 21 move. When the reset rod 21 moves, it pushes the first block 22 to move. The movement of the first block 22 makes the return spring 13 move. During the process that the return spring 13 moves and compresses the detection spring 14, the second block 32 abuts against the pull rod 31. The second block 32 pushes the pull rod 31 to compress the first return spring 33, and then the second block 32 is clamped with the pull rod 31 to limit the position of the return spring 13.

[0046] The operator continues to pull the protection cylinder 25. The protection cylinder 25 makes the reset rod 21 continue to move towards the push rod 41. The continuous movement of the reset rod 21 makes the push rod 41 abut against the linkage rod 42. During the process that the linkage rod 42 continues to move towards the push rod 41, the abutment of the push rod 41 and the linkage rod 42 makes the linkage rod 42 descend vertically. The vertical descent of the linkage rod 42 makes the reset rod 21 compress the second return spring 44, and then the push rod 41 is inserted into the slot 412. At this time, the reset rod 21 is away from the first block 22, and the reset rod 21 will not block the return spring 13 during its movement.

[0047] The operator pulls the pull rod 31, and the pull rod 31 is disengaged from the second clamping block 32. Under the action of the detection spring 14, the detection spring 14 pushes the return rod 13 to impact the wall. The hammer on the return rod 13 pushes the spring piece 151 so that the indicating rod 15 moves a certain distance in the third chute 213. Then the operator pushes the push rod 41 to move in the long slot 411 so that the push rod 41 moves away from the slot 412. The operator pushes the protection cylinder 25 so that the protection cylinder 25 shrinks into the box body 1. Under the action of the linkage gear 24 and the second rack 26, the first rack 23 returns to the initial position and the reset rod 21 returns to the initial position.

[0048] Then the operator moves the box body 1 towards the wall. During the movement of the box body 1 towards the wall, the measuring rod 17 moves. The movement of the measuring rod 17 causes the third rack 51 to move. The movement of the third rack 51 causes the control gear 52 to rotate. The rotation of the control gear 52 causes the detection rod 16 to rotate. When the end of the measuring rod 17 close to the wall is flush with the box body 1 and fits against the wall, the limit block 53 is inserted into the limit groove 531, and the detection rod 16 is in a vertical state. The operator observes the inclination of the wall by observing the angle formed by the detection rod 16 and the wall. Through the protection cylinder 25, the first driving assembly and the second driving assembly 5, it is realized that one instrument can measure multi-item wall data, reducing the amount of instruments carried by the operator.

[0049] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
