Description

Technical Field

[0001] The utility model relates to the technical field of channel support, in particular to a channel side wall supporting device. Background Art

[0002] Channels and rivers are constructed inside the channels because the excavation of channels is carried out. The soil on both sides of the channels is relatively soft due to the excavation and will be affected by rainy days, which will cause the channels to collapse easily. Therefore, channel support devices are needed to support and ensure the safety of construction workers and to shape the channels. At present, channel support devices mostly adopt a cross-arm support structure. This type of support device is very useful in the construction of vertical and horizontal channel side walls. However, when constructing channels with slope protection structures, the force arms when supporting on both sides are dispersed, and no vertical force arms are applied to the channel side walls, resulting in poor support effects. In view of this, in-depth research was conducted on the above-mentioned issues, and this case was created. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3The utility model provides an implementation scheme: in the modern channel construction process, in order to carry out channel operations, the channel side wall needs to be supported. The current support equipment often adopts a cross arm support 4 structure. This single cross arm support structure has an excellent support effect on the side wall perpendicular to the horizontal. However, for the channel side wall with an inclined angle, due to the angle of the channel side wall, the horizontal force arm of the cross arm is applied to the channel side wall and is decomposed, and it cannot provide a force arm perpendicular to the channel side wall, resulting in poor support effect.

[0022] Therefore, the present application discloses a channel side wall support device, the device is specifically divided into three independent parts, the first part is a channel travel component composed of a pair of sliding seats 1 and a top pressure plate 2, which is used to move the lower structure for supporting the channel side wall, the second part is a pressure plate control seat 3 located below the top pressure plate 2 and connected by a height adjustment structure 14, which is used to push downward to provide a pushing effect, and the third part is composed of a cross arm support 4 connected to the pressure plate control seat 3 and a side wall support plate 6 connected to the cross arm support 4, which directly contacts the channel side wall and converts the top pressure force into a force arm vertical to the channel side wall;

[0023] Specifically, a pair of slide seats 1 are symmetrically arranged and the tops are welded and connected by a top pressure plate 2. A pressure plate control seat 3 is arranged in parallel below the top pressure plate 2. A pair of cross arm supports 4 are extended from both ends of the pressure plate control seat 3. When implemented, the pair of slide seats 1 are arranged in parallel on the ground on both sides of the ditch and can move forward in parallel. Rollers and roller brake devices are arranged on the slide seats 1. The top pressure plate 2 is connected to the pair of slide seats 1 to play a role of lateral support. A height adjustment structure 14 is arranged on the top pressure plate 2 to adjust the height of the pressure plate control seat 3. The pair of cross arm supports 4 are lowered or lifted, and the posture of the side wall support plate 6 is adjusted through the pair of cross arm supports 4 as an extension connection;

[0024] Specifically, a pair of side wall support plates 6 match the angle of the channel slope, a reinforcing support seat 7 is fixed at the center of the side wall support plate 6, a threaded hole is provided on the pushing seat 8 of the reinforcing support seat 7, and the threaded hole is aligned with the pushing screw 13 on the cross arm support 4;

[0025] Furthermore, in order to match the orientation of the channel side wall, a sliding groove 9 is provided on the cross arm support 4, and the position of the sliding positioning seat 10 is adjusted by the sliding groove 9. A rotating sleeve 11 is provided on the sliding positioning seat 10, and the orientation of the pushing screw 13 can be adjusted by the rotating sleeve 11. A positioning pressure seat 12 is provided on the rotating sleeve 11, and a threaded hole is provided on the positioning pressure seat 12. The cooperation between the threaded hole and the pushing screw 13 can adjust the position and orientation of the pushing screw 13, so that the axial direction of the pushing screw 13 is aligned with the axial direction of the reinforcing support seat 7, and then the pushing screw 13 on the sliding positioning seat 10 is threaded into the reinforcing support seat 7, and the reverse thrust of the reverse action of the thread pushes the reinforcing support seat 7, so that the downward vertical force arm is converted into a force arm perpendicular to the side wall support plate 6.

[0026] Furthermore, a pair of reinforcing ribs 5 are connected between the pair of cross arm supports 4 and the pressure plate control seat 3 , and the pair of reinforcing ribs 5 are used to strengthen the supporting effect of the pair of cross arm supports 4 .

[0027] Furthermore, the positioning press seat 12 and the rotating sleeve 11 are integrally formed to form a plate with a semi-oblong circular cross-section, which can improve the overall structural strength of the positioning press seat 12 and the rotating sleeve 11.

[0028] Furthermore, the sliding groove 9 is a rectangular structural through groove opened on the cross arm support 4, the sliding positioning seat 10 is a rectangular structural plate matching the shape of the sliding groove 9, and the sliding positioning seat 10 and the sliding groove 9 are transitionally matched. When the pushing screw 13 forms a stable threaded connection with the pushing seat 8 on the reinforcing support seat 7, the positions of the sliding groove 9 and the sliding positioning seat 10 will be fixed.

[0029] Furthermore, a cylindrical rod is arranged at the center of the sliding positioning seat 10, and a rotating sleeve 11 is sleeved on the cylindrical rod, so that the cylindrical rod enables the rotating sleeve 11 to rotate around the cylindrical rod as the axis, thereby adjusting the direction of the positioning pressure seat 12 so that the pushing screw 13 is aligned with the pushing seat 8.

[0030] Furthermore, the reinforcing support seat 7 is a cross-shaped plate connected to the side wall support plate 6 by bolts, and the reinforcing seat with a cross-shaped structure can reinforce the side wall support plate 6 in all directions.

[0031] From the above, it can be generally known that the channel side wall support device adopts a top pressure plate 2 design that spans the channel. The position of the top pressure plate 2 can be adjusted through the height adjustment structure 14, so that the cross arm support 4 drives the side wall support plate 6 to match and press fit onto the channel side wall. The pushing screw 13 connected to the side wall support plate 6 through the cross arm support 4 pushes and squeezes the reinforcing support seat 7. The pushing screw 13 changes the force of the side wall support from parallel to the horizontal to perpendicular to the channel side wall, thereby providing a better support effect.
