Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline supporting devices, and in particular relates to a pipeline supporting frame for the construction of a water conservancy pump station. Background Art

[0002] A hydraulic pump station is a facility used to provide hydraulic energy and pump water from a low place to a high place or transport it through a pipeline. During the construction of a hydraulic pump station, pipeline support is a common requirement. The currently commonly used temporary support device adopts a U-shaped support frame structure, so that the pipeline is nested in the U-mouth to achieve a stable support. However, as a temporary support device, the support device needs to be removed after installation. In order to separate the support device from the pipeline, the bracket on the top of the support device needs to be significantly lowered to move and separate it, resulting in the inability to further improve the efficiency of the installation. Utility Model Content

[0003] The utility model aims to provide a pipeline support frame for the construction of a water conservancy pump station, so as to more conveniently separate the support device from the pipeline.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pipe support frame for water conservancy pump station construction, comprising a base plate, a lifter and a support seat, the fixed end of the lifter is connected to the top surface of the base plate, the telescopic end of the lifter is connected to the bottom of the support seat, a limited position seat is installed above the support seat, the support seat comprises a first arc-shaped plate body, the limit position seat comprises a second arc-shaped plate body, the first arc-shaped plate body and the center axis of the second arc-shaped plate body coincide with each other, and the bottom surface of the second arc-shaped plate body is slidably connected to the upper surface of the first arc-shaped plate body, the top surface of the second arc-shaped plate body is a concave arc surface, and limited positions are arranged on both sides of the first arc-shaped plate body. The cam is an angular movement movement mechanism which is adapted to move the second arcuate plate body in a direction opposite to the first arcuate plate body and to move the second arcuate plate body in a direction opposite to the first arcuate plate body.

[0005] Preferably, the bottom surface of the second arc plate body is provided with a plurality of limit grooves at intervals along its length direction to form a rack structure; support shafts are rotatably provided at both ends of the length direction of the first arc plate body, the axis of the support shaft is parallel to the center axis of the first arc plate body, and a support wheel is coaxially fixedly provided in the middle of the support shaft, and the outer peripheral surface of the support wheel has convex teeth matching the limit grooves, so that the support wheel and the bottom surface of the second arc plate body form a gear rack transmission structure; one end of the support shaft is provided with a pressing sleeve that rotates synchronously with the support shaft, and the end surface of the pressing sleeve away from one end of the support shaft is provided with an axial plug hole, a threaded column is fixedly provided on the outer surface of the limit plate, a pressure plate is sleeved on the threaded column, and plug-in columns corresponding to the axial plug-in holes on the pressure sleeve are fixedly provided at both ends of the pressure plate, and the limiter includes a knob, which is threadedly connected to the threaded column on the outer surface of the limit plate, and the knob is arranged on the side of the pressure plate away from the limit plate, and the knob is used to limit the axial position of the pressure plate on the threaded column.

[0006] Preferably, a handle is installed on the outer curved surface of the second curved plate.

[0007] Preferably, the lifter is a hydraulic structure, the axis of the lifter is vertically arranged, and the telescopic end of the lifter is connected to the center position of the bottom surface of the first arc-shaped plate body; the length of the second arc-shaped plate body is greater than the length of the first arc-shaped plate body, the slide groove is centrally arranged relative to the second arc-shaped plate body, and the ends of the second arc-shaped plate body in the length direction are both convex relative to the corresponding ends of the first arc-shaped plate body.

[0008] Preferably, a plurality of rollers are installed at the bottom of the base plate.

[0009] The beneficial effects of the utility model are as follows: during implementation, the pipeline is placed on the concave curved surface at the top of the second curved plate body, and the first curved plate body is arranged at the bottom of the second curved plate body. The two curved plate bodies form a whole that supports the pipeline. When the pipeline is lifted, the plate body is not easily deformed and has stronger stability. After installation, the support seat only needs to be slightly lowered by the lifter (theoretically, it is only necessary that the surface of the second curved plate body does not contact the pipeline), so that the limiter switches to the first state, and the second curved plate body can be slid, so that the end of the second curved plate body slides toward the position close to the end of the first curved plate body, and a clearance position can be generated at the end positions of the two curved plate bodies, so that the support device and the pipeline are completely separated.

[0010] The utility model is more flexible and convenient to install and implement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] 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.

[0017] See also Figure 1-Figure 4 The utility model includes a base plate 1, a lifter 3 and a support seat 5. The fixed end of the lifter 3 is connected to the top surface of the base plate 1, and the telescopic end of the lifter 3 is connected to the bottom of the support seat 5. A limit seat 6 is installed above the support seat 5. The support seat 5 includes a first arc-shaped plate body 54, and the limit seat 6 includes a second arc-shaped plate body 61. The first arc-shaped plate body 54 and the second arc-shaped plate body 61 have a central axis that coincides with the axis of the circle, and the bottom surface of the second arc-shaped plate body 61 is slidably connected to the upper surface of the first arc-shaped plate body 54, and the top surface of the second arc-shaped plate body 61 is an inner concave arc surface. According to the above description, the first arc-shaped plate body 54 and the second arc-shaped plate body 61 are both plate-like structures extending in the direction of the arc line, and the inner concave arc surfaces (or simply referred to as inner arc surfaces) of both are facing upward.

[0018] Limiting plates 51 are provided on both sides of the first arc-shaped plate body 54, and the limiting plates 51 limit the axial movement of the second arc-shaped plate body 61. A sliding shaft 53 is installed on the surface of the limiting plate 51, and the sliding shaft 53 and the sliding grooves 63 on both sides of the second arc-shaped plate body 61 are nested with each other. The extension direction of the sliding groove 63 is consistent with the sliding direction of the second arc-shaped plate body 61 relative to the first arc-shaped plate body 54. The cooperation between the sliding shaft 53 and the sliding groove 63 can guide the second arc-shaped plate body 61 on the one hand, and limit the radial movement of the second arc-shaped plate body 61 on the other hand. A limiter 52 is provided between the first arc-shaped plate body 54 and the second arc-shaped plate body 61 for controlling the switching between the first state of relative movement and the second state of relative locking. The end of the second arc-shaped plate body 61 is convex relative to the end of the first arc-shaped plate body 54, and the length of the convexity can be adjusted by the sliding of the second arc-shaped plate body 61 relative to the first arc-shaped plate body 54. Comparison Figure 1 and Figure 4 It can be seen that Figure 1 In normal use, the left end of the second arc-shaped plate 61 is convex relative to the left end of the first arc-shaped plate 54. Figure 4 When sliding in the counterclockwise direction as shown, the protruding length of the left end of the second arc-shaped plate 61 relative to the left end of the first arc-shaped plate 54 becomes shorter, and an air avoidance area is generated in the left area of ​​the two arc-shaped plates, and the pipeline can be completely separated from the supporting device from this air avoidance area.

[0019] The lifter 3 can adopt various conventional lifting devices. The utility model preferably adopts a hydraulic structure, and the axis of the lifter 3 is arranged vertically. The lifter 3 can use its own control handle 4 to control the lifting switch. The control handle 4 is an existing mature technology and is not described in detail in the utility model. In order to achieve reliable support of the top structure, the telescopic end of the lifter 3 is preferably connected to the center of the bottom surface of the first arc plate 54. The second arc plate 61 is preferably designed to be longer than the length of the first arc plate 54, and the chute 63 is centered relative to the second arc plate 61 (that is, the chute 63 and the second arc plate 61 are symmetrically arranged as a whole, and the symmetry plane is a cross section through the center position of the length direction of the second arc plate 61), and the ends of the second arc plate 61 in the length direction relative to the corresponding ends of the first arc plate 54 are all convex. That is, under normal use, the second arc plate 61 is centered relative to the first arc plate 54. When it is necessary to separate the pipeline and the supporting device, the second arc-shaped plate 61 can slide in both directions and can be flexibly selected according to actual conditions. Figure 4 The embodiment shown is a counterclockwise sliding, and a clearance area is generated in the left area of ​​the two arc-shaped plates. Figure 1 The structure shown is the initial state, the second arc-shaped plate 61 is along Figure 4If the sliding direction is opposite to the direction of the arc plate (i.e., clockwise), a clearance area can be generated in the right area of ​​the two arc-shaped plates.

[0020] The structure of the limiter 52 can be various. For example, the most common one is to arrange one or more locking screws on the moving stroke of the second arc-shaped plate 61. When the locking screws are loosened, the second arc-shaped plate 61 can slide; when the locking screws are tightened, the second arc-shaped plate 61 is relatively fixed. In order to make the structure more reliable, the preferred solution adopted by the utility model is that the bottom surface of the second arc-shaped plate body 61 is provided with a plurality of limit grooves 64 at intervals along its length direction to form a rack structure; support shafts 525 are rotatably provided at both ends of the length direction of the first arc-shaped plate body 54, and the axis of the support shaft 525 is parallel to the central axis of the first arc-shaped plate body 54; a support wheel 524 is coaxially fixedly provided in the middle of the support shaft 525, and the outer peripheral surface of the support wheel 524 has convex teeth matching the limit grooves 64, so that the support wheel 524 and the bottom surface of the second arc-shaped plate body 61 form a gear rack transmission structure; one end of the support shaft 525 is provided with a pressing sleeve 523 which rotates synchronously with the support shaft 525, and the support shaft 525 and the pressing sleeve 523 can be designed as an integral structure, or can be connected and fixed by a bolt structure. An axial plug hole is provided on the end face of the pressing sleeve 523 away from the support shaft 525, a threaded column is fixedly provided on the outer surface of the limiting plate 51, a pressing plate 522 is sleeved on the threaded column (i.e., a hole is provided in the middle of the pressing plate 522 for the threaded column to pass through), plug-in columns corresponding to the axial plug holes on the pressing sleeve 523 are fixedly provided at both ends of the pressing plate 522, and the limiter 52 includes a knob 521, which is threadedly connected to the threaded column on the outer surface of the limiting plate 51, and the knob 521 is provided on the side of the pressing plate 522 away from the limiting plate 51, and the knob 521 is used to limit the axial position of the pressing plate 522 on the threaded column. When the plug-in column is not inserted into the axial plug hole on the pressing sleeve 523, when the force applied to the second arc-shaped plate body 61 is large enough, the second arc-shaped plate body 61 can slide normally, and the support shaft 525 can rotate normally. When the plug-in column is inserted into the axial plug-in hole on the pressing sleeve 523, the pressing plate 522, the threaded column and the two support shafts 525 are connected as a whole, and the support shafts 525 cannot rotate freely. Due to the limiting effect of the convex teeth on the support wheel 524 on the second arc-shaped plate 61, the second arc-shaped plate 61 cannot move relative to the first arc-shaped plate 54. At this time, tightening the knob 521, the pressing plate 522 cannot retreat (that is, the plug-in column cannot be separated from the pressing sleeve 523), and the overall support structure is relatively stable. When the position of the second arc-shaped plate 61 needs to be adjusted, the knob 521 can be loosened, and the pressing plate 522 can retreat to the position where the plug-in column and the pressing sleeve 523 are separated, and the second arc-shaped plate 61 can slide normally.

[0021] In order to facilitate the movement of the second arc-shaped plate 61, a handle 62 is installed on the outer arc surface of the second arc-shaped plate 61. The handle 62 can be arranged at any end of the second arc-shaped plate 61, or at both ends.

[0022] In order to facilitate the movement of the entire device, a plurality of rollers 2 are installed at the bottom of the base plate 1. The rollers 2 are preferably running wheels with built-in brakes.
