Description

Technical Field

[0001] The utility model belongs to the technical field of continuous beam construction, and relates to a construction monitoring device, in particular to a short-term video monitoring device used for continuous beam construction. Background Art

[0002] In linear projects such as railways and highways, continuous beam bridges are widely used in large-span construction sections such as across roads and rivers due to their advantages such as large span, good stability and easy construction.

[0003] During the construction of continuous beams, concrete maintenance is a crucial link. Prestressing requires that the compressive strength of concrete reaches 95%, the elastic modulus is greater than 100%, and it can only be carried out after the age exceeds 5 days. Whether the maintenance is in place is directly related to the speed of concrete strength growth, and then to the progress of a series of subsequent tensioning, grouting, hanging basket walking and other construction. The maximum beam height of the 100m continuous beam is 7.29m for block 0, and the minimum beam height is 4.69m at the joint section. Due to the high beam height and the narrow and steep hanging basket escalator, the inner box room is full of debris after the formwork is removed, making it inconvenient to enter. Therefore, during maintenance, the work team will focus on the bridge deck that is easy to operate, and pay less attention to the maintenance of the inner box room.

[0004] Whether the inner box room is maintained or not often requires on-site technicians to go to the site to check and verify in person. However, the beam is high, and before the middle span is closed, the T-structures on both sides are not interconnected. It takes at least an hour to climb up and down the ladder cage and hanging basket to enter the inner box room and check all the T-structures of the two main piers, which takes up a lot of time and energy.

[0005] In view of the above situation, the utility model proposes a short-term video monitoring device for continuous beam construction to realize the monitoring of the inner box room, improve the monitoring efficiency, reduce the labor intensity of manual monitoring, and ensure the maintenance quality of the inner box room. Summary of the invention

[0006] The purpose of the utility model is to provide a short-term video monitoring device for continuous beam construction which has a scientific and reasonable structural design, improves monitoring quality, reduces labor intensity, improves monitoring safety, ensures the quality of inner box room maintenance, and is easy to implement.

[0007] The utility model solves the technical problem through the following technical solutions:

[0008] A short-term video monitoring device for continuous beam construction is characterized in that it includes a power supply mechanism, a connecting rod, a tripod, a camera mounting head and a camera, wherein the tripod is installed on the connecting rod, the power supply mechanism is hinged on the upper end of the connecting rod, the camera mounting head is installed on the lower end of the connecting rod, and the camera is installed on the camera mounting head.

[0009] Moreover, the power supply mechanism is a solar panel, and a hinged ear is provided at the upper end of the connecting rod. The solar panel is hinged on the hinged ear through a mounting plate at the back of the solar panel.

[0010] Moreover, the connecting rod is a telescopic rod, including an upper sleeve rod and a lower adjustment rod. Adjustment holes are longitudinally spaced on the upper sleeve rod, and a spring pin is provided on the lower adjustment rod. The lower adjustment rod is sleeved on the upper sleeve rod, and the relative position of the lower adjustment rod with the upper sleeve rod is adjusted by the extension and retraction of the spring pin in the adjustment hole.

[0011] Moreover, the tripod is a level tripod, and the connecting rod is installed in the middle of the tripod.

[0012] Moreover, the camera mounting head includes a camera slot, a mounting side plate, a connecting sleeve, a fastening ring and an angle adjustment knob. The camera slot is placed vertically, and mounting side plates are symmetrically arranged on both sides of the back of the camera slot. A connecting sleeve is rotatably installed between the two mounting side plates. The connecting sleeve is limited by a top screw arranged on one side of the mounting side plate, and an angle adjustment knob is arranged at the end of the top screw. A fastening ring with an internal thread is connected to the upper part of the connecting sleeve, and the fastening ring is threadedly connected to the external thread made on the connecting rod, and the camera is inserted into the camera slot.

[0013] The advantages and beneficial effects of the utility model are:

[0014] This short-term video monitoring device used in continuous beam construction can monitor the situation inside the continuous beam box room. When maintenance is not being carried out inside the box room, it can be discovered at the first time and the work team can be notified in time, so that the inspectors can reduce the frequency and number of verification visits, and monitor the maintenance quality in real time to ensure adaptation to environmental changes.

[0015] The installation process is highly assembly-oriented. One person only needs half an hour to complete the forward movement and assembly of the device, saving manpower and material resources.

[0027] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely descriptive and not restrictive, and the protection scope of the present invention cannot be limited by them.

[0028] The second section of the new Shihengcanggang intercity railway Henghuang section project is 41.934 kilometers long, mainly including the construction of "two bridges and one station", including 1.82km of section and station roadbed, 40.114km / 2 mainline super-large bridges (18.791km Qingliangjiang super-large bridge, 21.323km Fucheng cross-281 provincial highway super-large bridge), and there are 6 continuous beams in the whole section, including 1 main span of 100m, 1 main span of 80m, 3 main spans of 64m, and 1 main span of 48m. All standard sections of continuous beams adopt the cantilever casting construction technology of hanging basket. This utility model takes 60+100+60m continuous beams as the construction background. In order to solve the practical problem of weak maintenance in the box room, this utility model is proposed.

[0029] During the construction of the continuous beam, some holes with a diameter of 10 cm and 12 cm will be reserved for the anchoring of the hanging basket or for the convenience of passing water pipes and wires from the beam surface into the box room. After the construction of the beam body is completed, they will be uniformly blocked. The reserved holes are used to arrange the utility model, which ensures that the on-site disassembly and installation are convenient and can be operated by one person.

[0030] A short-term video monitoring device for continuous beam construction, the innovation of which lies in: comprising a power supply mechanism, a connecting rod 3, a tripod 2, a camera mounting head 4 and a camera 5, the power supply mechanism is a solar panel 1, a tripod is installed on the connecting rod, a hinged ear is provided at the upper end of the connecting rod, the solar panel is hinged on the hinged ear through a mounting plate on its back, a camera mounting head is installed at the lower end of the connecting rod, and the camera is installed on the camera mounting head.

[0031] In order to adapt to continuous beams of different thicknesses, the connecting rod is a telescopic rod to facilitate length adjustment, which includes an upper sleeve rod 6 and a lower adjustment rod 7. Adjustment holes 9 are longitudinally spaced on the upper sleeve rod, and a spring pin 8 is provided on the lower adjustment rod. The lower adjustment rod is sleeved on the upper sleeve rod, and the relative position with the upper sleeve rod is adjusted by the extension and retraction of the spring pin in the adjustment hole.

[0032] The tripod is a level instrument tripod, which ensures the overall stability of the device and reduces the influence of uneven beam surface. The connecting rod is installed in the middle of the tripod.

[0033] The camera mounting head includes a camera slot 14, a mounting side plate 13, a connecting sleeve 11, a fastening ring 10 and an angle adjustment knob 12. The camera slot is placed vertically, and mounting side plates are symmetrically arranged on both sides of the back of the camera slot. A connecting sleeve is rotatably installed between the two mounting side plates. The connecting sleeve is limited by a top screw arranged on one side of the mounting side plate, and an angle adjustment knob is arranged at the end of the top screw. A fastening ring with an internal thread is connected to the upper part of the connecting sleeve, and the fastening ring is threadedly connected to the external thread made on the connecting rod, and the camera is inserted into the camera slot.

[0034] Working principle:

[0035] The monitoring device is divided into a bridge deck part, a box interior part and a middle connecting rod. The bridge deck part is mainly used to support the tripod of the entire monitoring device and the solar panel for energy supply, while the box interior is mainly used for monitoring cameras. The solar panel is connected to the connecting rod through a screw rod, which allows the solar panel to adjust its angle at will to better receive light. The middle connecting rod is connected to the monitoring camera in the box interior, and the camera lowering height can be adjusted through the telescopic rod to adapt to different top plate cross-sectional thicknesses. The three components are all connected by sockets and spigots to ensure that no other tools are required on site and to ensure the convenience of movement.

[0036] Working process:

[0037] As the continuous beam is continuously cantilevered forward, the monitoring device is also constantly moved and placed in a position where it will not affect the construction and can clearly monitor the situation inside the box. The tripod is fixed on the beam surface, the telescopic rod is connected to the monitoring device, and the total length is adjusted by the length of the push-type pin on the connecting rod. The monitoring device is extended into the box through the holes reserved in the previous construction of the bridge deck. The upper part of the connecting rod is connected to the tripod and the solar panel. After normal power supply, the camera can monitor the scene inside the continuous beam box anytime and anywhere.

[0038] The cameras used for monitoring are powered by data traffic and solar panels. There is no need to lay wires or network cables, and there is no need to employ professional electricians to connect the electricity. They can be assembled by technical management personnel. At the same time, on-site wiring can also be carried out using the maintenance gate box, making full use of prefabricated operations and on-site conditions.

[0039] The continuous beam section is relatively high, and there is no condition to hang monitoring equipment in the box. If the monitoring screws are fixed on the concrete surface, the monitoring cycle at each position is short and it is very inconvenient to move it repeatedly. The monitoring camera is placed on a tripod, and all three tripods are equipped with sockets. The technicians can move it as needed without the help of other personnel, thus solving this problem.

[0040] This monitoring device can not only monitor indoor maintenance, but also move the video to the top after maintenance is completed to monitor the key construction positions of the hanging basket. It is highly applicable to key temporary construction points with short time and high strength, such as pier body pad stone construction, monitoring on-site material transportation, temporary component processing, etc. It can strengthen the supervision of some key positions in open areas and has strong adaptability to conditions.

[0041] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will appreciate that various substitutions, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
