Description

TECHNICAL FIELD

[0001] The utility model relates to bridge load test field, concretely relates to a pay-off and take-up device of individually paying off and integrally taking up. BACKGROUND

[0002] Bridge load test is the most direct method for testing whether the bridge carrying capacity meets the requirements, and the main detection parameters of bridge load test are strain and deflection. The strain testing elements include integrated strain gauges, vibrating wire strain gauges and displacement sensors, among which the integrated strain gauges are widely used due to their quick installation and accurate force measurement. According to the different bridge structure forms, the arrangement positions of strain gauges are different, especially for the bridge with large width, the number of strain gauges arranged is large, and the arrangement range is distributed along the bridge width. If the bridge span geological condition is good and the clearance under the bridge is low, the preparation work such as patching can be directly carried out at the bottom of the bridge. However, in the actual bridge load test process, the test preparation work is mainly carried out on the bridge inspection vehicle as the operation platform.

[0003] In actual operation, the loading process of bridge load test is relatively fast, but a large amount of time is consumed for the previous preparation work, and the wiring work of strain gauges is time-consuming and tedious, the main reason is to save the cost of load test detection, and the length of the wiring end of the purchased strain gauge is generally only about 1m, the standby line needs to be connected at the wiring end, and the length of the standby line needs to be ensured to be connected with the collector on the bridge surface. Since the strain gauges are distributed along the bridge width, the length of each wiring is different, that is, different lengths of standby lines are needed for different bridges, and different lengths of standby lines are also needed for the same bridge. If the wires are cut into different lengths, the work will be complicated, if the same length of wire is used, the ends of the wires will be of different lengths, which is troublesome to arrange and affects the work efficiency.

[0004] In order to solve the above problems, the utility model discloses a device with the same length of each winding disc, single winding disc independently paying off, and multiple winding discs integrally and centrally taking up. SUMMARY

[0005] The utility model aims at providing a pay-off and take-up device of individually paying off and integrally taking up, which can freely stretch and contract the wiring according to the actual situation, improve the detection efficiency of load test, and reduce the time cost.

[0006] In order to achieve the above purpose, the utility model has the following scheme:

[0007] The utility model discloses a kind of wire laying and winding devices of integral winding of single wire laying, by mobile trolley and the winding device of being set to its inside, the mobile trolley is provided with gyro wheel, and the gyro wheel is provided with the car body of one side opening by top plate, bottom plate, side plate, a plurality of transverse bulkheads are arranged between the top plate and the bottom plate, and the side plate is provided with horizontal rod rod slot on the upper portion of the side plate.

[0008] The winding device includes a horizontal rod, a plurality of winding discs, and an adjustable speed motor. The main shaft of the winding disc is hollow and composed of two sections of wire discs with different diameters. A flange shared by the two sections of wire discs is provided with a wire threading hole. The horizontal rod passes through the main shaft of the winding disc, and the two ends of the horizontal rod pass through the horizontal rod slot on the side plate. One end of the horizontal rod is provided with an adjustable speed motor connected to the horizontal rod.

[0009] Among them, the larger diameter side of the two sections of wire discs is a wire head winding disc, and the smaller diameter side is a wire tail winding disc. The main part of the wire is wound on the wire head winding disc, and the wire tail part is wound on the wire tail winding disc through the wire threading hole of the winding disc.

[0010] Further, a winding disc anchoring ring is arranged on the flange outside the wire head winding disc, and a plurality of horizontal rod anchoring bolt holes are arranged on the horizontal rod. The winding disc and the horizontal rod are connected through the winding disc anchoring ring and the horizontal rod anchoring bolt holes to form an integral whole.

[0011] Still further, the horizontal rod is connected to the adjustable speed motor, and the winding disc, the horizontal rod, and the adjustable speed motor are connected as an integral whole through bolts.

[0012] Preferably, the winding device further includes an external horizontal rod and a wire guide hole. The external horizontal rod is arranged on the side of the opening of the car body, and the external horizontal rod is provided with a movable wire guide hole. The wire guide hole can move along the external horizontal rod to uniformly wind the wire on the winding disc during the wire recovery process.

[0013] During the wire laying process, the anchoring bolts are removed to separate the winding disc from the horizontal rod. Each winding disc can lay wire individually. After the wire is laid to the appropriate length, the wire head is connected to the strain gauge, and the wire tail is connected to the strain collector. After the data collection is completed, the connection between the wire head and the strain gauge and the connection between the wire tail and the strain collector are disconnected.

[0014] During the wire winding process, the anchoring bolts are used to connect each winding disc to the horizontal rod to connect the winding disc, the horizontal rod, and the adjustable speed motor as an integral whole. The winding disc is synchronously wound by turning on the adjustable speed motor.

[0015] The utility model has the following beneficial effects:

[0016] This utility model is applicable to the patching process in the test preparation stage and the wire recovery process after the test in bridge load testing. This utility model only requires one wire length, and only requires the preparation of several reels of the same wire length in the early stage, which can be applied to load test projects of different bridge widths in the later stage, simplifying the work method and improving work efficiency.

[0017] Multiple reels can be installed on the same horizontal bar. When unloading, the wire can be unloaded separately. If the unloaded wire is too long, the reel can be rotated to reel it in. When reeling in, multiple reels can be retracted at the same time, or the wire can be retracted separately when adjusting. It is suitable for a variety of wire unloading and reeling needs.

[0018] No manual arrangement is required during the winding and reeling process. Simply adjust the position of the wire hole during the winding process to ensure that the wire on the reel is wound evenly.

[0019] The device is designed as a storage cabinet, which protects the cable and prevents data acquisition from being affected by direct sunlight or damaged by rain.

[0020] The partition shelves of this device can be selectively installed and removed to adjust the spacing, making it suitable for different scenarios and needs, and highly practical.

[0021] The transverse partition platform of this device can also be used as a storage platform, which has a high space utilization rate. In addition to the cable reel installation area, the empty space can be used as an auxiliary instrument storage area. It can store the auxiliary instruments and equipment required for load testing, avoid the influence of the external environment on the data acquisition device during the test data acquisition process, and facilitate the staff to organize, shorten the preparation time, carry out the test and inspection work in an orderly manner, and improve work efficiency.
