Description

Technical Field

[0001] The utility model relates to a contact network compensation device, in particular to a limiting frame for a weight. Background Art

[0002] The contact network provides compensation through the tensioning force provided by the weight, and provides guidance and restriction for the weight to avoid the influence of wind swing and other phenomena on the weight. The weight is restricted and guided by setting a restriction frame. The traditional restriction frame constrains the weight clamp by setting a conduit between the upper beam and the lower beam. When setting the conduit, bolts are usually used to fix the two ends of the conduit to the upper beam and the lower beam. This installation method is inconvenient. At the same time, the long-term wind swing of the weight hits the conduit, causing the bolts to loosen, which can easily cause the conduit to fall off. In addition, the accumulated water in the conduit cannot be discharged in time, which makes it easy to crack after freezing. Utility Model Content

[0003] In order to solve the problems in the prior art that the conduit is easy to loosen by threaded connection and is inconvenient to install, and the conduit is not drained in time, the technical solution adopted by the utility model is:

[0004] A weight fixing and limiting frame comprises an upper crossbeam and a lower crossbeam, a conduit for limiting and guiding the weight clamp is arranged between the upper crossbeam and the lower crossbeam, an upper mounting plate and a lower mounting plate are respectively arranged on the upper crossbeam and the lower crossbeam, an upper sleeve and a lower sleeve are respectively arranged on the upper mounting plate and the lower mounting plate, two ends of the conduit are respectively inserted into the upper sleeve and the lower sleeve and installed and positioned between the upper crossbeam and the lower crossbeam, and a drainage hole communicated with the lower sleeve is also arranged on the lower mounting plate.

[0005] Furthermore, a bolt pin capable of locking the catheter is provided on the upper casing and / or the lower casing.

[0006] Furthermore, a waist-shaped hole for the bolt pin to pass through is provided on the upper sleeve or the lower sleeve provided with the bolt pin.

[0007] Furthermore, the upper mounting plate and the lower mounting plate are respectively fixed to the upper crossbeam and the lower crossbeam by U-shaped bolts.

[0008] By adopting the above scheme, when installing the catheter, you only need to insert the two ends of the catheter into the sleeve to achieve positioning installation, which is convenient and quick to install; and because a drainage hole connected to the lower sleeve is provided on the lower mounting plate, when water accumulates in the catheter, the accumulated water can be discharged through the drainage hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 is a schematic diagram of the restraining frame structure;

[0010] Figure 2 It is a schematic diagram of the upper mounting plate and the casing structure;

[0011] Figure 3 It is a schematic diagram of the lower mounting plate and the lower casing structure; DETAILED DESCRIPTION

[0012] Figure 1 The limiting frame shown includes an upper crossbeam 1 and a lower crossbeam 2 installed on the column B, an upper mounting plate 4 is arranged on the upper crossbeam 1, and a lower mounting plate 5 is installed on the lower crossbeam 2. An upper sleeve 6 is arranged on the upper mounting plate 4, and a lower sleeve 7 is arranged on the lower mounting plate 5. A guide tube 3 is arranged between the upper crossbeam 1 and the lower crossbeam 2. When installing the guide tube 3, the two ends of the guide tube 3 are respectively inserted into the upper sleeve 6 and the lower sleeve 7 for installation and positioning. The installation is convenient and quick.

[0013] The upper mounting plate 4 and the lower mounting plate 5 are respectively connected and fixed to the upper beam 1 and the lower beam 2 by U-shaped bolts 11. Taking the upper mounting plate 4 as an example, a through slot 12 is specifically provided on the upper mounting plate 4. The U-shaped bolts 11 are fastened to the upper beam 1. The two ends of the U-shaped bolts 11 are passed through the through slots 12. After the nuts 13 are connected to the two ends of the U-shaped bolts 11, the nuts 13 are tightened to fix the upper mounting plate 4 to the upper beam 1. The lower mounting plate 5 is installed in the same way. When the upper mounting plate 4 and the lower mounting plate 5 are installed on the upper beam 1 and the lower beam 2, the positions are adjusted and then the nuts 13 are tightened to ensure that the conduit 3 remains in the vertical direction.

[0014] In order to drain the water in the catheter (3) in time, Figure 3 As shown, a drainage hole 8 is opened on the lower mounting plate 5, and the drainage hole 8 is communicated with the lower sleeve 7. When there is condensed water or rainwater on the inner wall of the conduit 3, it flows into the lower sleeve 7 under the action of gravity and is discharged in time from the drainage hole 8 to ensure that no water accumulates in the conduit 3.

[0015] To further ensure safety and reliability, Figure 1 As shown, bolt pins 9 are provided on the upper sleeve 6 and the lower sleeve 7 to lock the conduit 3, so that the conduit 3 is connected with the upper mounting plate 4 and the lower mounting plate 5. When the upper mounting plate 4 or the lower mounting plate 5 is loosened and falls off, it is ensured that the limiting frame will not fall apart as a whole, which is convenient for subsequent maintenance and repair. Of course, the risk of the conduit 3 falling off is the most important, so in addition Figure 1 In the embodiment, the bolt pin 9 is arranged on both the upper sleeve 6 and the lower sleeve 7. Alternatively, the bolt pin 9 can be arranged on either the upper sleeve 6 or the lower sleeve 7. When the bolt pin 9 is arranged specifically, as shown in FIG. Figure 2Taking the upper sleeve 6 as an example, a waist-shaped hole 10 is provided on the upper sleeve 6, and a through hole 14 is provided on the upper end of the conduit 3. After the upper end of the conduit 3 is inserted into the upper sleeve 6, the bolt pin 9 is passed through the waist-shaped hole 10 and the through hole 14, so that the conduit 3 is locked with the upper sleeve 6. The locking method of the lower end of the conduit 3 and the lower sleeve 7 is the same, which will not be repeated. As for the purpose of providing the waist-shaped hole 10 on the upper sleeve 6 and the lower sleeve 7, the purpose is to facilitate the assembly and installation of the conduit 3, to allow for axial adjustment with a margin, to reduce the positioning accuracy of the through hole 14 on the conduit 3, and to ensure that the bolt pin is not subjected to additional shear force.

[0016] During installation, the upper mounting plate 4 can be first fixed to the predetermined position of the upper crossbeam, and then the conduit 3 can be inserted into the upper sleeve 6 and locked into the upper sleeve 6 by the bolt pin 9 to keep it in a vertical state. Then, the lower sleeve 7 can be inserted into the lower end of the conduit 3, and the lower mounting plate 5 can be fixed while keeping the conduit 3 in a vertical state. Finally, the lower end of the conduit 3 can be locked with the lower sleeve 7 by the bolt pin 9.

[0017] When in use, the weight clamp A is set on the catheter 3 so that it can move axially along the catheter 3. Since the weight clamp A is limited and guided by the catheter 3, the weight fixed in the weight clamp A can move along the specified direction, and the catheter 3 can also limit the swing of the weight.
