Abstract
Description
Technical Field
[0001] The utility model relates to a mechanical adjusting device, in particular to an adjusting device for the horizontal displacement of a counterweight. Background Art
[0002] At present, for the counterweight clamp of the counterweight restraint frame at the dead end of the catenary of electrified railways, usually one end is fixed to the counterweight string, and the other end is connected to the restraint conduit by the clamp method. When the wire expands and contracts, it pulls the connected counterweight string to move up and down along the restraint conduit under the frame of the counterweight clamp to complete the dead end tension compensation. In actual work, affected by factors such as the accumulation of installation errors, vibration during equipment operation, and changes in the geological environment, the position of the counterweight string or the restraint conduit may shift. However, due to the fixed size of the traditional counterweight clamp, the distance between the counterweight string and the restraint conduit cannot be adjusted. When the distance changes, excessive mutual pulling forces will be generated, resulting in an increase in friction between the restraint conduit and the counterweight clamp, hindering the normal movement of the counterweight string along the restraint conduit, and even may cause problems such as bending deformation of the restraint conduit, jamming, and deflection of the counterweight string, seriously threatening the safety of power supply equipment. The prior art lacks a counterweight device that can be horizontally adjusted conveniently and quickly. Summary of the Utility Model
[0003] To solve the problems and defects of the components proposed in the above background art, the utility model provides a circular counterweight horizontal displacement adjusting device.
[0004] To achieve the above object, the technical solution provided by the utility model is as follows:
[0005] A circular counterweight horizontal displacement adjusting device, which includes: two groups of symmetrically arranged counterweight clamps, a restraint pipe clamp, and an adjusting bolt. It is characterized in that: the adjusting bolt passes through adjusting nuts welded on both sides of the transverse plate of the restraint pipe clamp and is in threaded cooperation with the limit nuts arranged on the outermost sides of the two horizontal cross plates of the "day"-shaped frame of the counterweight clamp. The adjusting bolt rotates around its own axis. The limit nuts are in contact with the outermost horizontal cross plate surface but not fixed, and are connected to the adjusting bolt by split pins and keep coaxial rotation to prevent loosening. By the threaded cooperation of the adjusting bolt and the adjusting nuts, the transverse plate of the restraint pipe clamp is driven to move along the axial direction of the adjusting bolt, so as to adjust the distance between the transverse plate and the horizontal cross plate of the "day"-shaped frame, and realize the horizontal displacement of the counterweight clamp.
[0006] For further improvement, one end of the weight carrier hoop is a single ear, and the other end is a "day"-shaped frame composed of two horizontal cross plates and two vertical plates. Through holes are provided at the centers of the two horizontal cross plates and are perpendicular to the two vertical plates. A positioning plate with a through hole is welded to the shorter inner vertical plate. The positioning plate is perpendicular to the vertical plate, and its length is the same as the distance between the two single ears, and its width is the same as the vertical height of the shorter inner vertical plate. The positioning plates in the two symmetrically arranged weight carrier hoops are symmetrically arranged relative to each other. The positioning bolts connect the symmetrically arranged upper and lower positioning plates, and the fastening bolts connect the two single ears, forming a symmetrically arranged weight carrier hoop structure.
[0007] For further improvement, the restraint pipe hoop is of a semi-circular structure. A vertical plate with a through hole is provided on the outer side of the starting point of the semi-circular arc. The vertical plate is fixed to the end position of the restraint pipe hoop by welding and is parallel to the chord of the semi-circular arc. On the outer side of the center point of the semi-circular arc of the restraint pipe hoop, a horizontal plate with a through hole is provided and is perpendicular to the chord of the semi-circular arc. A through hole is opened at the center of the horizontal plate, and an adjusting nut is welded to each of the two side surfaces of the through hole. The adjusting nut is fixed to the two side surfaces of the horizontal plate by welding and is used for threaded cooperation with the adjusting bolt. The vertical plate with a through hole of the restraint pipe hoop is connected to another vertical plate with a through hole arranged symmetrically through a connecting bolt, forming the symmetrically arranged restraint pipe hoop structure to ensure the overall stability.
[0008] For further improvement, the adjusting bolt includes a screw rod with a full-thread structure, two limit nuts and an opening pin. The limit nuts are installed at the positions of the through holes on the outermost sides of the two horizontal cross plates of the weight carrier hoop. The limit nuts are in contact with the horizontal cross plates but not fixed. A through hole is opened at the center position of the side surface of the limit nut and is connected to the adjusting bolt through an opening pin to ensure that the limit nut rotates coaxially on the adjusting bolt. Two through holes are provided at the end of the screw rod of the adjusting bolt, and the through holes are aligned with the through holes of the limit nuts, and the limit nuts are fixed to the adjusting bolt through an opening pin to ensure that the adjusting bolt can effectively drive the horizontal plate of the restraint pipe hoop to move axially during rotation.
[0009] By the above technical solutions, the following beneficial effects are achieved by the present utility model:
[0010] The present utility model designs a circular weight horizontal displacement adjusting device. The device drives the horizontal plate of the restraint pipe hoop to move axially through the adjusting bolt to realize the horizontal displacement adjustment of the weight carrier hoop, and at the same time changes the surface-to-surface friction between the weight carrier hoop and the restraint conduit into surface-to-line friction, thereby reducing the friction resistance and solving the problems of difficult adjustment and large friction caused by fixed dimensions in the prior art.
[0011] The pipe clamp provided by the utility model is composed of two semi-circular steel rings. The vertical plate and the horizontal plate with through holes are fixed by bolts and connected to the adjusting bolt. The threaded fit driving design is scientific. The end of the adjusting bolt is provided with a through hole connected to the limit nut and fixed by an opening pin. The overall structure is stable and reasonable.
[0012] This device is applicable to the multi-angle adjustment of the catenary counterweight in the horizontal direction of electrified railways, which is flexible and easy to operate. Brief Description of the Drawings

It is characterized in that: the adjusting bolt 4 passes through adjusting nuts 21 welded on both sides of the transverse plate 2 of the restricting pipe clamp 1, and is in threaded cooperation with a limiting nut 41 arranged at the outermost side of the two horizontal cross plates 61 of the "day"-shaped frame of the weight clamp 5. The adjusting bolt 4 rotates around its own axis. The limiting nut 41 is in surface contact with the outermost horizontal cross plate 61 but not fixed, and is connected to the adjusting bolt 4 through an opening pin 42 and rotates coaxially to prevent loosening. By the threaded cooperation between the adjusting bolt 4 and the adjusting nut 21, the transverse plate 2 of the restricting pipe clamp 1 is driven to move axially along the adjusting bolt 4, so as to adjust the distance between the transverse plate 2 and the horizontal cross plate 61 of the "day"-shaped frame, and realize the horizontal displacement of the weight clamp 5.
[0022] As Figure 2 shown in the figure, one end of the weight clamp 5 is a single ear 7, and the other end is a "day"-shaped frame composed of two horizontal cross plates 61 and two vertical plates 62. Through holes are arranged at the centers of the two horizontal cross plates 61 and are perpendicular to the two vertical plates 62. A positioning plate 63 with a through hole is welded to the shorter inner vertical plate 62. The positioning plate 63 is perpendicular to the vertical plate 62, its length is the same as the distance between the two single ears 7, and its width is the same as the vertical height of the shorter inner vertical plate 62. The positioning plates 63 in the two symmetrically arranged weight clamps 5 are symmetrically arranged relative to each other. A positioning bolt 64 connects the upper and lower symmetrically arranged positioning plates 63, and a fastening bolt 71 connects the two single ears 7 to form a symmetrically arranged structure of the weight clamp 5.
[0023] As Figure 3 shown in the figure, the restricting pipe clamp 1 has a semicircular structure. A vertical plate 3 with a through hole is arranged outside the starting point position of its semi-circular arc. The vertical plate 3 is fixed to the end position of the restricting pipe clamp 1 by welding and is parallel to the chord of the semi-circular arc. Outside the center point position of the semi-circular arc of the restricting pipe clamp 1, a transverse plate 2 with a through hole is arranged and is perpendicular to the chord of the semi-circular arc. A through hole is opened at the center of the transverse plate 2, and an adjusting nut 21 is welded to each of the two side surfaces of the through hole. The adjusting nut 21 is fixed to the two side surfaces of the transverse plate 2 by welding and is used for threaded cooperation with the adjusting bolt 4. The vertical plate 3 with a through hole of the restricting pipe clamp 1 is connected to another vertical plate 3 with a through hole arranged symmetrically through a connecting bolt 31 to form a symmetrically arranged structure of the restricting pipe clamp 1 to ensure overall stability. The vertical plate 3 is outward relative to the two horizontal cross plates 61 for easy installation.
[0024] As Figure 4As shown in the figure, the adjusting bolt 4 includes a screw rod with a full-thread structure, two limit nuts 41 and a split pin 42; the limit nuts 41 are installed at the positions of the through holes on the outermost sides of the two horizontal cross plates 61 of the counterweight hoop 5. The limit nuts 41 are in contact with the horizontal cross plates 61 but not fixed. Through holes are provided at the central positions on the sides of the limit nuts 41 and are connected to the adjusting bolt 4 through the split pin 42 to ensure that the limit nuts 41 rotate coaxially on the adjusting bolt 4; two through holes are provided at the end of the screw rod of the adjusting bolt 4. The through holes are aligned with the through holes of the limit nuts 41, and the limit nuts 41 are fixed to the adjusting bolt 4 through the split pin 42 to ensure that the adjusting bolt 4 can effectively drive the lateral plate 2 of the limit pipe hoop 1 to move axially during rotation; in actual operation, after the split pin 42 passes through the through holes at the end of the limit nut 41 and the adjusting bolt 4, the limit nut 41 is fixed on the screw rod and cannot move axially, but can rotate coaxially with the adjusting bolt 4.
[0025] As Figure 5 shown in the figure, the limit pipe hoop 1 and the limit conduit 8 are connected in a ring shape by a hoop. The limit pipe hoop 1 can rotate 360 degrees around the axis of the limit conduit 8. The counterweight string 9 can also rotate at multiple angles and adjust its displacement in the horizontal direction with respect to the limit conduit 8.
