Abstract

The utility model relates to a quadrupod for grouting and belongs to a device for grouting in the hydropower construction work. The quadrupod comprises an underframe and support rods and is characterized in that the underframe is of a horseshoe-shaped structure formed by I-shaped steel, steel pipes are respectively arranged on four corners of the underframe to form the support rods, and the other ends of the steel pipes are positioned and connected side by side by pin rods. The quadrupod has the beneficial effects that 1, after the quadrupod is used as a bracket, especially the shape of the underframe is similar to the horseshoe shape, the bracket and a drill are formed into a whole, so that the contact area between the drill and a platform is increased, the stability of the drill is strong, a cantilever beam is not easy to be bent by stretching by a drill rod during pull out of a hole, the quadrupod is not easy to collapse and deform, the occurrence probability of safety accidents is greatly reduced, and therefore the self safety of operators is further ensured; 2, the quadrupod is simple in structure, convenient to assemble and convenient for popularization and application.

Description

A kind of grouting quadrupod

Technical field

A kind of grouting quadrupod belongs to grouting device in the construction of hydropower facilities engineering.

Background technology

The grouting platform if will normally carry out grouting construction, must be set up in the power station poor at geological conditions, that the toe board gradient is steep.Land lengths mostly is about 6m, and plank is laid on top.At present, when setting up the grouting platform, often adopt tripod as the rig support.Because the tripod contact area is little, the grouting hole depth is many at 80～150m again, so during deep hole construction, drilling rod weight is big, the platform Oscillation Amplitude is bigger during construction, and the sky beam causes tripod to cave in, be out of shape easily by the drilling rod stretch bending easily during trip-out, the generation security incident.

Summary of the invention

Problem to be solved in the utility model is exactly the support of setting up the grouting platform that a kind of good stability is provided at above deficiency.Its technical scheme is as follows:

It comprises underframe and pole, and its key technology is that underframe constitutes horseshoe-shaped structure by i iron, steel pipe is installed respectively on four jiaos of underframe is constituted pole, and the other end of steel pipe is located by connecting side by side by pin rod.

Compared with prior art, the beneficial effect that the utlity model has is:

1, adopt quadrupod as support after, particularly the underframe shape is similar to the shape of a hoof, support and rig form an integral body, the contact area of rig and platform is increased, the stability of rig is strong, and the sky beam is difficult for by the drilling rod stretch bending during trip-out, and quadrupod is difficult for caving in, being out of shape, reduce occurrence probability of safety accidents greatly, thereby further guarantee operating personnel's inherently safe.

2, simple in structure, easy to assembly, easy to utilize.

The specific embodiment

Referring to Fig. 1-Fig. 4, the utility model comprises underframe 3 and pole 2, its key technology is that underframe 3 constitutes horseshoe-shaped structure by i iron, steel pipe is installed respectively on four jiaos of underframe is constituted pole 2, earlier processing is flattened in four steel pipe junctions before installing, the other end of steel pipe is located by connecting side by side by pin rod 1.

Underframe 3 is connected to integral body with rig 4, increases the contact area of rig and platform, is convenient to operation.

Claims

1. grouting quadrupod, comprise underframe (3) and pole (2), it is characterized in that underframe (3) constitutes horseshoe-shaped structure by i iron, steel pipe be installed respectively constituted pole (2) that the other end of steel pipe is located by connecting side by side by pin rod (1) on four jiaos of underframe.

2. according to the described grouting quadrupod of claim 1, it is characterized in that being connected to integral body at underframe (3) and rig (4).
