Description

Technical Field

[0001] The utility model relates to the field of cable protection devices, in particular to a cable wiring drag protection device for a gantry crane trolley. Background Art

[0002] The gantry crane used in the pump station is also called a gantry hoist, which is mainly used to open and close the gate, adjust the water flow, and perform maintenance and lifting. The external cables of the gantry crane trolley room are wires used to power the gantry crane. The existing cable dragging device generally uses a walking clamp, which moves the cable on the guide rail to move the gantry crane trolley. Therefore, this method makes the walking clamp and the cables on it directly exposed to the natural environment for a long time. After a long period of erosion by the sun and rain, the cables show obvious cracking and aging, and the walking clamp is also severely affected by rust. What is particularly serious is that the gantry crane cable will produce unreasonable local force problems under the dragging of the existing dragging device, especially the clamping position between the walking clamp and the cable is subject to greater force. Multiple frequencies of force cause the internal cable to break, affecting the travel of the trolley. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0019] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] like Figure 1-4 As shown, a cable wiring drag protection device for a gantry crane trolley comprises a bracket, the bracket having a horizontal support table 2 arranged along the travel direction of the gantry crane trolley 11, the upper surface of the horizontal support table 2 is provided with a closed wire trough 3 along its length direction, one end of the closed wire trough 3 is connected to one end of a closed support chain 7 arranged on the horizontal support table 2 (the connection here can be made by a connecting piece, such as a pin shaft, a bolt, etc., or one end of the closed support chain 7 can be inserted into the closed wire trough 3 for direct connection), the other end of the closed support chain 7 is connected to the machine room 10 of the gantry crane trolley 11 through a connector 8, and the travel cable of the gantry crane trolley 11 passes through the closed wire trough 3, the closed support chain 7 and the connector 8 in sequence and is led to the inside of the machine room 10 of the gantry crane trolley 11, and is connected to the main power supply inside the machine room 10.

[0021] Furthermore, the structure of the bracket is specifically composed of a plurality of columns 1, each of which is an I-beam structure, and the plurality of columns 1 are arranged at intervals along the traveling direction of the gantry crane trolley 11, mainly for supporting purposes.

[0022] Furthermore, the structure of the above-mentioned closed wire duct 3 specifically includes a front side plate 302, a rear side plate 301, a bottom plate 303 and a cover plate 304. The front side plate 302 and the rear side plate 301 are vertically connected to the bottom plate 303. The bottom plate 303 has a first connecting hole 12, and is fixed to the horizontal support table 2 by arranging a first connecting member in the first connecting hole 12. The cover plate 304 is engaged between the front side plate 302 and the rear side plate 301. The above-mentioned first connecting member uses screws or bolts to fix the bottom plate 303.

[0023] Furthermore, in order to reduce the welding area, the front side plate 302, the rear side plate 301 and the bottom plate 303 are an integrally formed structure, and the integrally formed structure has high strength, which can avoid cracking at the joints due to long-term use.

[0024] Furthermore, since the distance along the traveling direction of the gantry crane trolley 11 is long, in some cases, the length of a closed wire duct 3 is not enough. Therefore, in this case, multiple closed wire ducts 3 are provided, and the multiple wire ducts are arranged end to end. Second connecting holes 6 are correspondingly provided at both ends of the front side plate 302 and the two ends of the rear side plate 301. The front side plates 302 of two adjacent closed wire ducts 3 and the rear side plates 301 of two adjacent closed wire ducts 3 are respectively connected by connecting plates 4. The connecting plates 4 are provided with third connecting holes 5. Second connecting members are provided in the second connecting holes 6 and the third connecting holes 5. The second connecting members are bolts and nuts. The connecting plates 4 are connected between the two front side plates 302. At the same time, the connecting plates 4 are also connected between the two rear side plates 301. Then, bolts are used to pass through the second connecting holes 6 and the third connecting holes 5 to achieve connection. This connection method is also relatively easy to replace or disassemble and wash.

[0025] Furthermore, the structure of the above-mentioned connecting head 8 is specifically an inverted U-shaped groove. When in use, the horizontal plate of the inverted U-shaped groove is located on the upper side, and the cables are arranged below the horizontal plate. In this way, the horizontal plate of the inverted U-shaped groove can protect the cables. A plurality of supporting bars 9 are provided between the two side plates of the inverted U-shaped groove. The supporting bars 9 can support the cables to prevent them from falling. In order to ensure the connection rigidity, one end of the horizontal plate of the inverted U-shaped groove is connected to the closed support chain 7 by bolts, and the other end is connected to the machine room 10 of the gantry crane trolley 11 by bolts. At the same time, this connection method is also convenient for disassembly.

[0026] Furthermore, the connector 8 is L-shaped as a whole, and the L-shaped corners are rounded. The connector 8 is set to the above shape in order to buffer the stress at the connection between the connector 8 and the closed support chain 7. When the connector 8 drives the closed support chain 7 to curl upward, the connection will be subjected to a large force. Therefore, the connector 8 extends a certain distance along the length direction of the closed support chain 7, which can buffer the pulling force on the connector 8 here and reduce the deformation here.

[0027] Furthermore, in order to reduce the degree of rust of the bracket and the horizontal support platform due to being in the natural environment for a long time, the outer periphery of the bracket and the horizontal support table 2 is painted with anti-rust paint.

[0028] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0029] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
