Abstract
The utility model relates to an anti-loosening connecting device for a crawler type drill jumbo chain, and belongs to the technical field of machinery. The anti-loosening connecting device for the crawler type drill jumbo chain comprises a connecting seat, wherein the end part of the connecting seat is fixedly provided with a plurality of connecting teeth, installing holes used for being assembled with the chain are formed in the connecting teeth, and fixing holes used for being fixed with a chain guide rail are also formed in the connecting seat. The anti-loosening connecting device has the advantages that the structure is simple, the installation is fast and convenient, and the chain can be effectively fixed and stretched, so the chain loosening and falling can be avoided, and the transmission performance of the chain can be obviously improved.
Description
Technical field
The utility model relates to a kind of thread off prevention connecting device of crawler mounted drill jumbo chain, belongs to field of mechanical technique.
Background technology
Crawler mounted drill jumbo is controlled the lifting of turret head by chain, current chain connection mode is reasonable not, becoming flexible, coming off easily appears in chain, affect the chain gear effect, cause the position control of turret head is difficult to realize accurate control, have a strong impact on work efficiency, therefore need the thread off prevention connecting device of a kind of crawler mounted drill jumbo chain of exploitation, reliable so that chain connects, the transmission effect of raising chain.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of thread off prevention connecting device of crawler mounted drill jumbo chain is provided.This thread off prevention connecting device is simple in structure, and it is convenient to install, and can effectively fix, the chain that stretches, thereby avoid chain-loose, come off, and can significantly improve the transmission performance of chain.
The technical scheme that its technical matters that solves the utility model adopts is:
The thread off prevention connecting device of crawler mounted drill jumbo chain, comprise Connection Block, described Connection Block end is fixed with some connection teeths, and described connection teeth is provided with for the mounting hole with chain assembling, on described Connection Block, also be provided with for the fixing fixed orifice of chain guide.The utility model also can be the chain buckle, is applicable to improve the chain gear of crawler mounted drill jumbo, as the device of strengthening the chain connection.Can, according to the size design of chain, have more fixing, drawing chain bar effect; By three the utility model can actv. fixing stretching chain, wherein two the utility model are arranged on the two ends of chain, connection teeth is connected with chain with the cooperation of bolt by mounting hole, then Connection Block was fixed by bolt and coordinating with chain guide of fixed orifice, realized the stretching to chain; Another is arranged on the middle part of chain, and Connection Block is fixed with the slide plate that drives the turret head lifting, be arranged on the utility model at middle part can be further fixing stretching chain, after therefore using the utility model, the transmission performance of chain improves greatly.
As preferably, described connection teeth is three or four, and described connection teeth uniform welding is fixed on the end of Connection Block.Connection teeth arranges three or four, can facilitate two or three chains in parallel.
As preferably, described Connection Block is provided with the rectangle fitting recess, and described fixed orifice has two, and described fixed orifice is located at respectively the both sides of fitting recess.On Connection Block, offer fitting recess, on the one hand save work material, in addition, due to the existence that fitting recess is arranged, Connection Block and chain guide or slide plate can be saved installing space fixedly the time, and fixed effect is better.
As preferably, one of them in described fixed orifice is tapped bore, and another is counterbore.The tail end of bolt gos deep into counterbore, avoids the bolt of giving prominence to tail end to affect chain gear.
As preferably, described connection teeth rounding.
The beneficial effects of the utility model are: the utility model is simple in structure, and tooling cost is low, and it is convenient to install, and can effectively fix, the chain of the crawler mounted drill jumbo that stretches, and significantly improves the transmission performance of chain.
The accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is the utility model birds-eye view;
Fig. 3 is left view of the present utility model.
In figure: 1, Connection Block, 11, fixed orifice, 12, fitting recess, 2, connection teeth, 21, mounting hole.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
The thread off prevention connecting device of crawler mounted drill jumbo chain as shown in Figure 1, Figure 2 and Figure 3, comprise Connection Block 1, described Connection Block 1 is processed with rectangle fitting recess 12, the two ends of fitting recess 12 are processed with two fixed orifices 11, one of them fixed orifice 11 is tapped bore, another fixed orifice 11 is counterbore, described Connection Block 1 end is welded with four connection teeths 2, on described connection teeth 2, be processed with for the mounting hole 21 with the chain assembling, connection teeth 2 and chain are fixed by mounting hole 21 and bolt, described connection teeth 2 roundings.
The utility model also can be the chain buckle, is applicable to improve the chain gear of crawler mounted drill jumbo, as the device of strengthening the chain connection.Can, according to the size design of chain, have more fixing, stretching chain; By three the utility model can actv. fixing stretching chain, wherein two the utility model are arranged on the two ends of chain, connection teeth 2 is connected with chain with the cooperation of bolt by mounting hole 21, then Connection Block 1 was fixed by bolt and coordinating with chain guide of fixed orifice 11, realized the stretching to chain; Another is arranged on the middle part of chain, and Connection Block 1 is fixed with the slide plate that drives the turret head lifting, be arranged on the utility model at middle part can be further fixing stretching chain, after therefore using the utility model, the transmission performance of chain improves greatly.
Above-described embodiment is a kind of preferably scheme of the present utility model, under the prerequisite that does not exceed the technical scheme that claim puts down in writing, also has other variant and remodeling.
