[0002] With the development of economy and the progress of society, the protection and restoration of cultural relics are also constantly improving and developing. The widespread application of various new technologies and new materials makes our restoration work more convenient, time-saving, safe and efficient. The re-pasting of hollows in mural ground layer diseases is an important part of our restoration work, and the support instrument is an indispensable tool for hollow repair. The commonly used support instrument does not display the strength during the support process. The support process can only rely on the experience accumulated over the years and the judgment of the surface status of the murals with hollow re-pasting diseases. Since the absorbent X60 paper and cotton paper need to be replaced during the support re-pasting process, the support wall panel needs to be removed during the replacement process. After the removal, the support gravity data is lost. It is not easy to grasp the strength and direction when replacing and supporting again. The support is time-consuming and labor-intensive, and the efficiency is low.

[0003] The inventor has found that the existing support device has at least the following disadvantages:

[0004] The existing restoration support frame does not have a gravity measurement function, and the support process can only rely on experience. After replacing the tissue paper, the support force cannot be well connected before and after, resulting in poor support effect and time-consuming and laborious support operation.

[0042] In the prior art, in work scenarios such as cultural relics restoration, it is necessary to repair hollow ground murals, and it is necessary to replace wall panels and other objects supporting the wall. The general operation is to first remove the original supporting components, and then replace them with new supporting components and use the support frame to support them again. Since the previous supporting force cannot be obtained, the subsequent supporting force only depends on the experience and judgment of the operators, which reduces the operating efficiency and it is difficult to ensure that the supporting forces before and after are basically consistent.

[0043] In view of this, the designer provides a cultural relic restoration pressure meter, which can obtain the supporting force provided each time the wall is supported in real time, so as to serve as a reference for the subsequent adjustment of the supporting force, improve work efficiency, and improve the stability and reliability of the support.

[0044] Please combine Figure 1-Figure 3 In this embodiment, the cultural relic restoration pressure meter is used in conjunction with a scaffold, and includes a support fixture 100, a force transmission screw 200, a pressure sensor 300 and a support top bracket 400; the support fixture 100 is provided with a threaded hole, the force transmission screw 200 is screwed with the threaded hole, and the support fixture 100 is used to be fixedly connected to the scaffold; the force transmission screw 200 and the pressure sensor 300 or the support top bracket 400 are rotatably matched, and the force transmission screw 200 and the pressure sensor 300 or the support top bracket 400 are relatively fixed in the length direction of the force transmission screw 200, and the pressure sensor 300 is installed between the force transmission screw 200 and the support top bracket 400; the support top bracket 400 is used to contact the wall.

[0045] Based on the above, the working mode of the cultural relic restoration pressure instrument provided in this embodiment is as follows:

[0046] When supporting the wall, the support fixture 100 is installed on the scaffold, and the support fixture 100 serves as a support point. The force transmission screw 200 is rotated, and the force transmission screw 200 is threadedly connected to the support fixture 100, and the support fixture 100 does not move, so that the force transmission screw 200 can move relative to the support fixture 100 along its own axis while rotating, thereby driving the support bracket 400 connected to the force transmission screw 200 to approach or move away from the wall. For example, when it is necessary to support objects such as wall panels located on the wall, the force transmission screw 200 drives the support bracket 400 to approach the wall, and the support bracket 400 can press the wall panels against the wall. During this process, due to the design of the pressure sensor 300, the force exerted by the supporting support 400 on the wall can be acquired in real time by the pressure sensor 300, thereby facilitating the operator to judge the magnitude of the applied force and ensuring that the subsequent supporting force can be used as a reference by the previous supporting force, so that the supporting forces provided by multiple supports are basically consistent, which is convenient for operation and improves work efficiency, and can also improve the stability and reliability of the support.

[0047] The details of the cultural relics restoration support device provided in this application are described below by way of examples.

[0048] In this embodiment, optionally, the support fixture 100 includes a positioning sleeve 110 and a fixing ring 120, the positioning sleeve 110 is fixedly connected to the fixing ring 120, a threaded hole is provided on the positioning sleeve 110, and the fixing ring 120 is used to be fixedly connected to the scaffolding.

[0049] It should be noted that the positioning sleeve 110 is convenient for connection with the force transmission screw 200, and the fixing ring 120 is convenient for connection with the scaffolding, and the two realize corresponding functions respectively and are easy to operate.

[0050] It should be understood that the positioning sleeve 110 can be a circular cylinder, and the cylinder cavity of the positioning sleeve 110 is a threaded hole, which is convenient for processing and manufacturing.

[0051] In addition, the positioning sleeve 110 can be rotatably matched with the fixing ring 120. For example, a rotating shaft is provided on the positioning sleeve 110, and an adapter cap is provided on the fixing ring 120. The rotating shaft and the adapter cap are rotatably matched through a bearing, and the rotation axis of the rotating shaft and the adapter cap is perpendicular to the axis of the threaded hole, that is, perpendicular to the axis of the force transmission screw 200. By setting the fixing ring 120 and the positioning sleeve 110 to be rotatably matched, in this way, the positioning sleeve 110 can be adaptively rotated, and the force transmission screw 200 is driven to rotate together by the positioning sleeve 110, and the support bracket 400 can be better driven to move by the force transmission screw 200, thereby improving the firmness of the contact between the support bracket 400 and the wall surface.

[0052] Please combine Figure 2 In this embodiment, optionally, the fixing ring 120 includes a first half ring 121, a second half ring 122, a hinge shaft 123 and a locking pin 124. One end of the first half ring 121 and one end of the second half ring 122 are both rotatably matched with the hinge shaft 123, the other end of the first half ring 121 is provided with a first fixing hole, and the other end of the second half ring 122 is provided with a second fixing hole, and the locking pin 124 is simultaneously inserted into the first fixing hole and the second fixing hole, so that the first half ring 121 and the second half ring 122 cooperate to define a positioning through hole for the rod of the scaffold to pass through; the first half ring 121 or the second half ring 122 is connected to the positioning sleeve 110. For example, in this embodiment, the middle position of the first half ring 121 is rotatably connected to the positioning sleeve 110.

[0053] It should be understood that when the fixing ring 120 is connected to the scaffold, the locking pin 124 is first removed from the first half ring 121 and the second half ring 122, so that the first half ring 121 and the second half ring 122 can be rotated to open, and then the first half ring 121 and the second half ring 122 are sleeved on the corresponding rods of the scaffold, such as steel pipes, and the first half ring 121 and the second half ring 122 are rotated to close, and then the locking pin 124 is simultaneously inserted into the first fixing hole and the second fixing hole, which is easy to operate. When the support fixture 100 needs to be removed, the locking pin 124 can be pulled out. The relative rotation of the first half ring 121 and the second half ring 122 is limited by the locking pin 124, and the locking effect is good.

[0054] It should be noted that the locking pin 124 can be a structural member such as a bolt, which can improve the stability and reliability of the connection.

[0055] Optionally, the inner circumference of the first half ring 121 and the inner circumference of the second half ring are both provided with an anti-slip layer. The anti-slip layer may be, but is not limited to, a rubber layer or a silicone layer.

[0056] It is worth noting that by setting the anti-skid layer, after the first half ring 121 and the second half ring 122 cooperate to clamp the rod of the scaffolding, the anti-skid layer contacts the rod, and the anti-skid layer can increase the friction force, thereby improving the firmness of the connection. The fixing ring 120 is tightly combined with the rod, not easy to loosen, and the position temperature is reliable.

[0057] In other embodiments, the anti-slip layer may be provided only on the first half ring 121 or the second half ring 122 , which can also play a role in increasing the binding force.

[0058] In this embodiment, optionally, an operating portion 210 for transmitting torque is provided at the end of the force transmission screw 200 away from the supporting bracket 400. By cooperating with the operating portion 210 through tools such as a screwdriver or a wrench, the torque can be transmitted to the force transmission screw 200 by rotating the tool, which saves time and effort, has high operating efficiency, is easy to operate, and is conducive to controlling the tightness.

[0059] For example, optionally, the operating portion 210 is provided with a coaxial outer hexagonal fitting surface and an inner hexagonal fitting hole.

[0060] With such a design, the operating portion 210 has a simple structure, and the outer hexagonal mating surface or the inner hexagonal mating hole can be selected as needed according to the type of tool, so it is flexible to use and has a wide adaptability.

[0061] In this embodiment, the cultural relic restoration pressure meter optionally further includes a display screen 500, the pressure sensor 300 is in communication connection with the display screen 500, the display screen 500 is installed on the support bracket 400, and the display screen 500 is used to display the pressure parameters obtained by the pressure sensor 300. Through the design of the display screen 500, when the force transmission screw 200 is operated to drive the support bracket 400 to abut against the wall, the pressure of the support bracket 400 acting on the wall surface can be obtained in real time, which is convenient for operation.

[0062] It should be understood that the display screen 500 can be configured to be an integrated structure with the pressure sensor 300, that is, the display screen 500 can be integrated on the housing of the pressure sensor 300 for easy installation.

[0063] In this embodiment, optionally, abutting protrusions 410 are provided on the support bracket 400, and the abutting protrusions 410 are used to contact the wallboard on the attached wall surface. There may be multiple abutting protrusions 410, which are distributed on the plate surface of the support bracket 400 for contacting the wallboard. The abutting protrusions 410 cooperate with the wallboard to improve the stability of the abutment.

[0064] Please combine Figure 3 In this embodiment, optionally, the force transmission screw 200 can be rotatably matched with the pressure sensor 300 through a bearing, and the bearing can reduce the rotational friction and can also transmit the axial force. The force transmission screw 200 and the inner ring of the bearing can be matched with a ball joint structure 600, which is convenient for adjusting the angle of the support bracket 400 to adapt to different wall support requirements and is flexible and convenient to use. It should be understood that the outer ring of the bearing is fixed together with the pressure sensor 300. When transmitting force, the force transmission screw transmits the supporting force through the inner ring to the outer ring, and then transmits it to the support bracket 400 through the pressure sensor 300.

[0065] The cultural relic restoration pressure meter provided in this embodiment, due to the design of the pressure sensor 300, the force exerted by the supporting jack 400 on the wall can be acquired in real time by the pressure sensor 300, thereby facilitating the operator to judge the size of the applied force and ensuring that the subsequent supporting force can be used as a reference by the previous supporting force, so that the supporting forces provided by multiple supports are basically consistent, which is convenient for operation and improves working efficiency, and can also improve the stability and reliability of the support.

[0066] This embodiment also provides a cultural relic restoration support system, which includes a scaffold and a cultural relic restoration pressure instrument, and the scaffold is connected to a support fixture 100 .
