Description

A fixed base for municipal construction road piles

Technical Field

The utility model relates to municipal road construction, in particular to a fixed base for municipal construction road piles.

Background technique

The utility model patent with the authorization announcement number CN211646114U and the patent name of a road pile for road construction discloses a road pile for construction. When in use, the rotating wheel 17 is rotated to drive the screw 4 to rotate, so that the movable plate 6 moves upward on the screw 4, so that the connecting rod 15 has a tendency to move horizontally, and pushes the two extended plates 13 to move outward, and then buries the soil until it is flush with the ground. The above scheme extends the extended plates 13 at both ends of the stabilizing component 3 to increase the contact area deep in the soil, effectively avoiding the situation that the road pile is easily impacted by external forces and becomes skewed when the soil is loose due to rain or the buried depth is shallow;

The utility model patent with the authorization announcement number CN217500017U and the patent name of a road pile for road construction discloses a road pile for construction, which solves the problem existing in the utility model patent with the authorization announcement number CN211646114U mentioned above. The problem existing in the above patent is that during the use of the device, a conical block is set to facilitate the device to be inserted into the soil, and then the stability is improved by the stabilizing components on both sides. However, the device is only fixed in the soil by the conical block. Once someone pulls it out, the device can be easily pulled out of the soil, which makes the stability of the device not good enough. In order to solve the above problem, the utility model patent with the authorization announcement number CN217500017U adopts a solution of rotating the rotating rod B702 to rotate the rotating rod B702 on the support, and at the same time, the fixing piece 703 on one side of the rotating rod B702 is inserted into the soil through the notches 704 on both sides of the cone head 6, and the friction of the cone head 6 on the soil is increased through the fixing pieces 703 on both sides, so that the fixing effect is better and it is not easy to be pulled out of the soil;

Through analysis, it can be known that the above two patents fix the road pile by inserting two protruding plates 13 and two fixing members 703 into the soil, respectively. Since the number of protruding plates 13 and fixing members 703 is limited, both are two, and the protruding length is also limited, the contact area with the soil is small and it is easy to be pulled out. Moreover, when the soil is loose on rainy days, the road pile is also prone to tilt due to fewer supporting points. At the same time, the above two utility model patents both adopt complex transmission relationships. The utility model patent with authorization announcement number CN211646114U adopts a screw nut structure, and the utility model patent with authorization announcement number CN217500017U adopts a transmission structure of a screw, gear and crawler. The transmission structure is complex, the operation is troublesome, and the cost is high. Moreover, after the road pile is buried underground, on rainy days, the mud mixed with water will enter the interior of the road pile cylinder through the protruding port 10 and the slot 704 on the road pile, which will affect the transmission mechanism, cause the screw to rust, and make it difficult to reuse.

Summary of the invention

In view of the above problems, the utility model provides a fixed base for municipal construction road piles to solve the above problems.

The technical solution is that the utility model comprises a cylinder, the lower end of which is conical, and a plurality of groups of through holes arranged up and down are opened on the cylinder, each group of through holes is composed of a plurality of through holes evenly distributed in a circle, and an L-shaped rod is hinged in each through hole, and a hinge shaft is placed in the through hole and at the bend of the L-shaped rod, so that one end of the L-shaped rod is placed in the cavity of the cylinder, and the other end is placed outside the cylinder;

There is a pull rod in the cavity of the cylinder, and the pull rod can move up and down. When the pull rod moves up and down, it drives the multi-layer L-shaped rods to rotate. When the pull rod is at the uppermost end of its displacement, the angle between the L-shaped rod placed outside the cylinder and the outer edge surface of the cylinder above it is an acute angle. When the pull rod moves from top to bottom, the L-shaped rod placed outside the cylinder rotates closer to the outer edge surface of the cylinder above it.

The pull rod can be fixed when it moves upward to the highest point or downward to the lowest point, so that the L-shaped rods of the multiple layers are also fixed.

The utility model has a compact structure and fixes the cylinder body by a plurality of L-shaped rods, which can not only increase the contact area with the soil, but also solve the problem that the cylinder body tilts when the soil is loose on rainy days. Furthermore, soil entering the cavity of the cylinder body will not cause damage to the structure, so that the cylinder body can be reused.

Detailed ways

The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

As shown in Figures 1 to 9, the utility model includes a cylinder 1, the lower end of the cylinder 1 is conical, and multiple groups of through holes arranged up and down are opened on the cylinder 1, each group of through holes is composed of multiple through holes evenly distributed in a circle, and an L-shaped rod 2 is hinged in each through hole, and the hinge shaft is placed in the through hole and at the bend of the L-shaped rod 2, so that one end of the L-shaped rod 2 is placed in the cavity of the cylinder 1, and the other end is placed outside the cylinder 1;

There is a pull rod 3 in the cavity of the cylinder 1, and the pull rod 3 can move up and down. When the pull rod 3 moves up and down, it drives the multi-layer L-shaped rod 2 to rotate. When the pull rod 3 is at the uppermost end of its displacement, the angle between the L-shaped rod placed outside the cylinder 1 and the outer edge surface of the cylinder 1 above it is an acute angle. When the pull rod 3 moves from top to bottom, the L-shaped rod 2 placed outside the cylinder 1 rotates closer to the outer edge surface of the cylinder 1 above it;

The pull rod 3 can be fixed when it moves upward to the highest point or downward to the lowest point, so that the multi-layer L-shaped rod 2 is also fixed.

In order to make the L-shaped rod 2 rotate when the pull rod 3 moves up and down and the L-shaped rod 2 is also fixed when the pull rod 3 is fixed, a plurality of toggle disks arranged up and down are fixed on the pull rod 3, each toggle disk corresponds to each layer of L-shaped rods one by one, and each toggle disk is composed of two upper and lower disks 4, and there is a gap between the two disks in each toggle disk. The pull rod 3 passes through the center of each disk 4, and the end of the L-shaped rod placed inside the cylinder 1 in each layer of L-shaped rod 2 corresponding to each toggle disk is inserted into the gap between the two disks 4.

When the L-shaped rod placed outside the cylinder 1 is in contact with the outer edge of the cylinder 1, the L-shaped rod placed inside the cylinder 1 is in an upwardly tilted state, and a lever 9 is fixed to the inner end of the L-shaped rod placed inside the cylinder 1. When the L-shaped rod placed outside the cylinder 1 is in contact with the outer edge of the cylinder 1, the lever 9 is in a horizontal state, and the lever 9 is placed in the gap between the two disks 4.

The upper end of the cylinder 1 is screwed with an end cover 5 via a thread. The end cover 5 is a cylinder with an open lower end. The upper end of the pull rod 3 is fixed on the end cover 5 and moves up and down on the end cover 5.

A cylinder 6 is fixed on the upper side surface of the upper end surface of the end cover 5, and the upper end of the cylinder 6 is open. The upper end of the pull rod 3 passes through the end cover 5 and is placed in the cylinder 6. A horizontal rod 7 is rotatably installed on the upper end of the pull rod 3. Two grooves with an angle of 90° are opened on the upper end surface of the cylinder 6, and the two grooves have different depths. A tension spring is mounted on the pull rod 3 outside the end cover 5, one end of the tension spring is fixed on the horizontal rod 7, and the other end of the tension spring is fixed on the end cover 5.

An arc-shaped plate is fixed to both the front and rear sides of the L-shaped rod 2 disposed outside the cylinder 1 , and the front and rear two flat plates and the L-shaped rod 2 form a complete arc-shaped plate 8 .

A road stake tube 10 is also installed above the base of the utility model. The road stake tube 10 is installed on the end cover 5 through a threaded or buckled structure.

When the utility model is used, a pit is first dug in the soil, and then the cylinder 1 and the end cover 5 are placed in the pit, and then the pull rod 3 is pulled upward through the horizontal rod 7, and the pull rod 3 drives the multi-layer L-shaped rod 2 to rotate on the cylinder 1 through the disks 4 on the multiple dials, so that the arc plate 8 on the L-shaped rod 2 outside the cylinder 1 rotates downward, increasing the angle between the arc plate 8 and the outer edge surface of the cylinder 1 above it, and then the horizontal rod 7 is placed in a shallow groove on the cylinder 6, and the horizontal rod 7 is stably placed in the groove on the cylinder 6 through the tension spring;

Then fill the pit with soil, bury a plurality of L-shaped rods 2 in the soil, so that a portion of the upper end of the end cover 5 extends out of the pit, and then install the road pile cylinder 10 on the end cover 5;

After use, first remove the road pile tube 10. Since the contact area between the multiple L-shaped rods 2 and the soil is large, the lifting tool can be used to tie the rope to the horizontal rod 7 to pull the base out of the pit. After pulling it out, operate the horizontal rod 7 to move the pull rod 3 downward, so that the multiple L-shaped rods 2 rotate, and the arc plate 8 rotates close to the outer edge of the cylinder 1 above it, reducing the volume of the cylinder 1 and the arc plate 8, which is convenient for subsequent transportation and centralized storage. After that, the horizontal rod 7 is placed in a deeper groove in the cylinder 6, and the horizontal rod 7 is kept stably placed in the groove of the cylinder 6 under the action of the tension spring.

The utility model arranges a plurality of rotating L-shaped rods 2 on the cylinder 1, and the plurality of L-shaped rods 2 can form a plurality of supporting points in the earth pit, which can not only increase the contact area with the soil, but also effectively prevent the cylinder 1 from tilting due to loose soil on rainy days;

An arc plate 8 is installed on the L-shaped rod outside the cylinder 1. When in use, the arc plate 8 greatly increases the contact area with the soil. In addition, since the angle between the arc plate 8 and the outer edge of the cylinder 1 above it is an acute angle, the existence of the acute angle enables the soil to exert a downward pressure on the cylinder 1 through the arc plate 8, thereby preventing the cylinder 1 from being pulled out at will when in use.

The utility model drives the L-shaped rod 2 to move up and down by the pull rod 3 and the up and down movement of the toggle plate on the pull rod 3. The structure is compact and the transmission efficiency is high. No structure such as threads is used. Even if muddy water and soil enter the cavity of the cylinder 1 through the through hole during use, it will not cause damage to the above structure and will not affect its repeated use.
