Description

Technical Field

[0001] The invention relates to the technical field of ancient building brick wall repair, and more specifically, to an auxiliary device for repairing and reinforcing ancient building brick walls. Background Art

[0002] With the development of the economy, the pace of urban transformation has accelerated, resulting in more or less damage to ancient buildings and cultural relics. Ancient buildings are important carriers of Chinese culture, telling us about China's 5,000-year history. The protection of ancient buildings cannot be ignored due to the modernization of cities. In general, there are five types of protection and repair of Chinese ancient buildings. The first is daily maintenance (i.e. regular maintenance); the second is protection and reinforcement; the third is current renovation; the fourth is key restoration; and the fifth is reconstruction on the original site.

[0003] The bricks used in most ancient buildings are deformed and fall off under long-term weathering, which leads to great safety hazards in ancient buildings. When repairing the brick walls of ancient buildings, it is not easy to construct at high positions, and auxiliary devices such as lifting platforms are required. However, brick wall repair may involve operations with strong destructive power such as drilling and removing old bricks. Such operations will cause certain damage to the ancient buildings during construction, and it is easy to cause objects (tiles, bricks, etc.) falling from the top of the wall. In severe cases, the ancient building may collapse. In view of this, the present invention provides an auxiliary device for repairing and reinforcing the brick walls of ancient buildings.

Openings for the slide plate to pass through are provided on opposite sides of the shell.

[0012] It is further preferred that: an alarm system is also included, the alarm system includes a sliding ball, an alarm, a sensor, a third spring and a controller;

[0013] The alarm is installed on the operating table, a cavity is provided in the vertical rod, one side of the sliding ball is provided on the side of the support rod close to the vertical rod, and the other side extends into the cavity and is connected with a flange, the third spring is located in the cavity and one end is connected to the flange, and the other end is connected to the inner wall of the cavity, and the sensor is installed in the cavity;

[0014] The vertical rod is located above the sliding ball, and the vertical rod is used to push the sliding ball to move into the cavity. The sensor is a displacement sensor and is used to detect the displacement information of the sliding ball and transmit the displacement information to the controller, and the controller controls the alarm to sound an alarm.

[0015] It is further preferred that: the alarm is a buzzer alarm.

[0016] Further preferably, a slide groove is provided on the inner wall of the housing, a convex strip is provided on the side of the sliding block, and the convex strip is inserted into the slide groove and slidably cooperates with the slide groove.

[0020] It is further preferred that: the base is provided with supporting legs.

[0021] In summary, the present invention has the following beneficial effects: the protection plate is mainly set to intercept falling objects from the top of the wall and improve construction safety. When falling objects from the top of the wall fall onto the protection plate, under pressure operation, the protection plate will drive the diagonal rod and the vertical rod to move downward. When the diagonal rod moves downward, the moving block will drive the slide plate to move horizontally toward the center of the protection plate on the support plate. Since the slide plate and the slider cooperate obliquely, when the slide plate moves horizontally toward the center of the protection plate, the slider moves upward in the shell, thereby applying a counter-impact force to the protection plate through the second spring. Under the buffering of the first spring and the second spring, the protection plate can be well protected, and the safety of the construction personnel is also improved. When the impact force of the object carried by the protection plate is too large and exceeds the preset value, that is, when the vertical rod moves downward by a distance exceeding the straight-line distance between the vertical rod and the sliding ball, as the vertical rod moves downward, the sliding ball is pushed into the cavity by the vertical rod. At this time, the alarm will sound an alarm, thereby reminding the construction personnel and other staff. After the objects on the protective plate are cleared, the protective plate is reset under the action of the first spring and the second spring. At this time, the vertical rod moves back to the top of the sliding ball, and the sliding ball is reset under the action of the third spring. It can be seen that whether it is falling objects from the top of the wall or building collapse, the protective plate can play a good role in protecting the construction work, reducing or avoiding injuries to construction workers, and solving the problem of insufficient safety when repairing the brick walls of ancient buildings.

The slider 87 is located in the shell 83 and slides up and down with the inner wall of the shell 83. Preferably, the inner walls on opposite sides of the shell 83 are provided with sliding grooves 88, and the lower sides of the opposite sides of the slider 87 are provided with convex strips 89 adapted to the sliding grooves 88. The convex strips 89 are inserted into the sliding grooves 88 and slide up and down with the sliding grooves 88. In order to prevent the slider 87 from detaching from the shell 83 upward, specifically, the sliding grooves 88 do not pass through the top of the shell 83.

[0033] The shell 83 is fixed on the support plate 12, and a trigger rod is provided at the bottom of the protective plate 7, and the trigger rod includes an inclined rod 131 and a vertical rod 132. One end of the inclined rod 131 is fixed to the bottom of the protective plate 7, and the other end extends downward in a direction away from the second spring 82 and is integrally connected to the upper end of the vertical rod 132. A moving block 85 that is slidably matched with the support plate 12 is provided on the top surface of the support plate 12. The moving block 85 slides in a direction away from or close to the shell 83. The moving block 85 is provided with an inclined hole that is adapted to the inclined rod 131 and is used for the inclined rod 131 to pass through.

[0034] Reference Figure 1-7The alarm system includes a sliding ball 91, an alarm 92, a sensor 93, a third spring 95 and a controller. The alarm 92 is installed on the operating table 5. Preferably, the alarm 92 is a buzzer alarm 92. A cavity 94 is provided in the vertical rod 132. One side of the sliding ball 91 is provided on the side of the support rod 11 close to the vertical rod 132, and the other side extends into the cavity 94 and is connected with a flange 96. The flange 96 is used to limit the sliding ball 91 from escaping from the cavity 94. The third spring 95 is located in the cavity 94 and one end is connected to the flange 96, and the other end is connected to the inner wall of the cavity 94. Two third springs 95 are provided, and the two third springs 95 are respectively located at the upper and lower sides of the cavity 94. The sensor 93 is installed in the cavity 94 and is located between the two third springs 95. The sensor 93 and the sliding ball 91 are respectively located at the horizontal ends of the cavity 94. The vertical rod 132 is located above the sliding ball 91, and the vertical rod 132 is used to push the sliding ball 91 to move horizontally into the cavity 94. When the falling object on the wall falls onto the protective plate 7, the protective plate 7 will drive the vertical rod 132 to move downward. When the impact force of the object carried by the protective plate 7 reaches a preset value, the vertical rod 132 moves downward by a distance exceeding the linear distance between the vertical rod 132 and the sliding ball 91. At this time, as the vertical rod 132 moves downward, the sliding ball 91 is pushed into the cavity 94 by the vertical rod 132. The sensor 93 is a displacement sensor 93 and is used to detect the horizontal displacement information of the sliding ball 91, and transmit the displacement information to the controller. The controller is electrically connected to the sensor 93 and the alarm 92 respectively, and the controller is used to control the alarm 92 to alarm.

[0035] In the present invention, the protection plate 7 is mainly set to intercept falling objects from the top of the wall and improve construction safety. When the falling objects from the top of the wall fall onto the protection plate 7, under pressure operation, the protection plate 7 will drive the diagonal rod 131 and the vertical rod 132 to move downward. When the diagonal rod 131 moves downward, the moving block 85 will drive the slide plate 84 to move horizontally toward the center of the protection plate 7 on the support plate 12. Since the slide plate 84 and the slider 87 are obliquely matched, when the slide plate 84 moves horizontally toward the center of the protection plate 7, the slider 87 moves upward in the shell 83, thereby applying a counter-impact force to the protection plate 7 through the second spring 82. Under the buffering of the first spring 81 and the second spring 82, the protection plate 7 can be well protected, and the safety of the construction workers is also improved. When the impact force of the objects carried on the protective plate 7 is too large and exceeds the preset value, that is, when the vertical rod 132 moves downwards to a distance exceeding the linear distance between the vertical rod 132 and the sliding ball 91, as the vertical rod 132 moves downwards, the sliding ball 91 is pushed into the cavity 94 by the vertical rod 132, and the alarm 92 will sound an alarm to alert the construction personnel and other staff. After the objects carried on the protective plate 7 are cleared, the protective plate 7 is reset under the action of the first spring 81 and the second spring 82, and the vertical rod 132 moves back to the top of the sliding ball 91, and the sliding ball 91 is reset under the action of the third spring 95.

[0036] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
