Description

Technical Field

[0001] The utility model relates to the technical field of monitoring, in particular to a PC continuous beam bridge construction monitoring device. Background Art

[0002] During bridge construction, monitoring devices are often needed to monitor the progress of the bridge and the work of workers on the construction site. For example, Chinese patent application number CN202122936639.9 discloses a bridge construction monitoring device.

[0003] However, monitoring devices in the prior art are usually installed using a fixed structure;

[0004] During construction, monitoring focus often shifts with each process (for example, from main beam monitoring to closing section monitoring). Fixed monitoring devices cannot flexibly adjust their position or angle based on actual monitoring needs, making it difficult to quickly focus on new critical points when needed.

[0005] To maximize coverage and minimize blind spots, existing solutions rely on increasing the number of fixed cameras, densely deploying them at different locations across the bridge. This significantly increases equipment procurement, installation, cabling, and maintenance costs, complicates the monitoring system, and makes data integration more difficult.

[0006] In summary, the fixed monitoring devices widely used in existing construction monitoring systems suffer from inherent structural limitations (immobility and fixed viewing angles), including limited field of view, numerous blind spots, inability to dynamically track construction progress and key points, high system costs, and limited flexibility. These issues severely restrict the real-time and flexibility of construction monitoring.

[0007] Therefore, there is an urgent need to develop a monitoring device that can overcome the above-mentioned defects and has mobility, so as to make real-time adjustments according to the construction progress and achieve more flexible and efficient dynamic monitoring.

[0008] Furthermore, the monitoring device also needs to have an effective braking structure to avoid parking and sliding. Utility Model Content

[0009] The purpose of the utility model is to provide a PC continuous beam bridge construction monitoring device to solve the problems raised in the background technology.

[0010] The above technical objectives of the present invention are achieved through the following technical solutions: a PC continuous beam bridge construction monitoring device, comprising a monitoring assembly; a conjoined base for assembling the monitoring assembly, rear rollers being provided on both sides of the rear end of the conjoined base, a rear shaft connected to the two rear rollers and a drive motor for providing rotational power to the rear shaft being provided inside the conjoined base; rotatable bending arms being provided on both sides of the front end of the conjoined base, an auxiliary wheel set being provided between the outer ends of the two bending arms; the auxiliary wheel set being separated from the ground in an initial state; the two bending arms being rotated upon receiving driving power so that the auxiliary wheel set contacts the ground;

[0011] A blocking block is fixedly provided at the bottom of the front end of the one-piece base. When the auxiliary wheel set is separated from the ground, the blocking block will contact the ground to increase friction resistance;

[0012] After the auxiliary wheel set comes into contact with the ground, the front end of the integrated base is lifted, so that the blocking block does not come into contact with the ground, thereby eliminating the friction resistance between the blocking block and the ground.

[0013] By adopting the above technical solution, the driving motor provides the power for the rear roller to rotate; the two bending arms can rotate relative to the front end of the integrated base, thereby driving the auxiliary wheel group to rotate synchronously; in the initial state, the block will contact the ground when the auxiliary wheel group is separated from the ground to increase the friction resistance; after switching to the moving state, the two bending arms will rotate, so that the auxiliary wheel group contacts the ground, and then lift the front end of the integrated base, so that the block does not contact the ground, thereby eliminating the friction resistance between the block and the ground; at this time, as the rear roller rotates, it can drive the monitoring component to move forward steadily.

[0014] A further configuration is that a wear-resistant layer is provided at the bottom of the block.

[0018] A first motor and a gear set are provided on the first front end frame. The first motor provides rotational power for the gear set, and the gear set provides rotational power for the bending arm and the transmission main shaft assembled in the first front end frame.

[0021] A first driven tooth is fixedly provided on the bending arm assembled in the first front end frame, and a first transmission belt is used to form a transmission between the first driven tooth and the third transmission tooth.

[0022] By adopting the above technical solution, meshing and transmission cooperation are achieved based on the gear set.

[0024] By adopting the above technical solution, through the cooperation of the second driven teeth, the fourth transmission teeth and the second transmission belt, the transmission main shaft can smoothly provide rotational power for the bending arm assembled in the second front end frame.

[0025] A further configuration is that the auxiliary wheel group includes fixed plates respectively fixed to the outer sides of the two bending arms, a transmission subshaft is rotatably arranged between the two fixed plates, and a plurality of auxiliary rollers are regularly arranged on the transmission subshaft, with intervals between adjacent auxiliary rollers.

[0026] By adopting the above technical solution and setting up multiple auxiliary rollers, the load-bearing capacity can be improved.

[0028] By adopting the above technical solution and providing two second motors, the driving capability is improved, thereby adapting to monitoring components with heavier weight.

[0029] Further, the monitoring assembly includes a monitoring base, the monitoring base is fixed to the upper end of the integrated base, a stepper motor, a rotating arm and a monitoring camera are provided inside the monitoring base, the monitoring camera is fixed to the rotating arm, and the stepper motor is connected to the rotating arm to control the rotation of the monitoring camera;

[0062] After switching to the mobile state, the first motor 44 controls the two bending arms 31 to rotate downward, so that the auxiliary wheel group contacts the ground, and as the two bending arms 31 continue to rotate downward, the front end of the connected base 21 can be raised so that the blocking block 23 does not contact the ground, thereby eliminating the friction resistance between the blocking block 23 and the ground; at this time, as the rear roller 22 rotates, it can drive the monitoring component 11 to move forward steadily.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed.
