Abstract
The utility model discloses a hydraulic excavator swing pipe device which comprises a swing pipe body, a short rocking rod, a spring device, a long rocking rod, a compression block and a connecting rod supporting body. The upper portion of the swing pipe body is connected with a bucket rod and a connecting rod of a hydraulic excavator. The lower portion of the swing pipe body, the short rocking rod, the long rocking rod and the connecting rod supporting body are hinged to form a parallelogram mechanism which plays a role in gravity clamping. The compression block is hinged to the long rocking rod. The compression block, the long rocking rod and the connecting rod supporting body form a clamping mechanism. The upper end of the spring device is hinged to the connecting rod supporting body, the lower end of the spring device is hinged to the swing pipe body, and the spring device plays a role in automatic reset. According to the hydraulic excavator swing pipe device, large-scale pipelines are carried and installed through the excavator by skillfully applying the parallelogram mechanism principle, the gravity clamping principle and the spring device automatic reset principle, and the hydraulic excavator swing pipe device has high efficiency, reliability and practicability.
Description
Technical field
The utility model relates to a kind of hydraulic excavator swing pipe device, for hydraulic excavator carrying and installation large-scale pipeline etc.
Background technology
Domestic Infrastructure building is various, and the large-scale pipelines such as city sewer, highway drainage road and engineering feed track, as the laying of concrete duct, repairing and safeguard enormous amount.Carrying and the installation of large-scale pipeline are to be completed by hoisting crane or excavating machine steel wire suspender at present, need special messenger be responsible for the binding of concrete duct and lighten restrictions on, the more loaded down with trivial details effort of process and dangerous.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of hydraulic excavator swing pipe device, can carry and install efficiently, fast, safely large-scale cement pipeline etc.
For addressing the above problem, technical solution of the present utility model is: a kind of hydraulic excavator swing pipe device, comprise swing pipe main body, short rocking bar, spring installation, long rocking bar, briquetting and link supports body, described short rocking bar one end and swing pipe main body are hinged, the other end and link supports body are hinged, long rocking bar one end and swing pipe main body are hinged, the other end and link supports body are hinged, swing pipe main body vertically maintains static, link supports body is under the effect of pipeline weight, by parallel-crank mechanism, with briquetting one work clamping pipe, i.e. gravity fastening.
Described briquetting is hinged with long rocking bar, and briquetting forms clamping mechanism with long rocking bar, link supports body, and spring installation upper end and link supports body are hinged, and lower end and swing pipe main body are hinged.When there is no pipeline Action of Gravity Field, spring installation overcomes after self gravitation, short rocking bar gravity, long rocking bar gravity and link supports body weight power, naturally reaches the longlyest, and the opening of swing pipe device is maximum, to facilitate, embed pipeline or unclamp pipeline, be i.e. the spring installation principle that automatically resets; When having pipeline Action of Gravity Field, spring installation is compressed.The opening of described swing pipe device is dehiscing of link supports body lower end and briquetting formation.
The contact surface of described link supports body and pipeline is arc.
Described swing pipe main body and short rocking bar, long rocking bar, link supports body form a parallel-crank mechanism.
Described briquetting and link supports body are hinged, make briquetting whenever can maximum area contact and compress pipeline, and the contact surface of briquetting and pipeline is arc.
Outstanding advantages of the present utility model is:
Adopted dexterously parallel-crank mechanism principle, gravity fastening and the spring installation principle that automatically resets, realized excavating machine and carry and install efficiently, fast, safely large-scale cement pipeline.
Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic excavator swing pipe device described in the utility model.
Fig. 2 is the clamping design sketch of hydraulic excavator swing pipe device described in the utility model.
Fig. 3 is the working effect figure of hydraulic excavator swing pipe device described in the utility model.
The specific embodiment
By drawings and Examples, the technical solution of the utility model is further illustrated below.
As shown in Figure 1 and Figure 2, hydraulic excavator swing pipe device described in the utility model, comprise swing pipe bucket body 1, short rocking bar 2, spring installation 3, long rocking bar 4, briquetting 5 and link supports body 6, described swing pipe main body 1 top is connected with dipper, the connecting rod of hydraulic excavator, and its underpart forms a parallel-crank mechanism by articulated form and short rocking bar 2, long rocking bar 4, link supports body 6.Briquetting 5 is hinged with long rocking bar 4, and briquetting 5 forms clamping mechanism with long rocking bar 4, link supports body 6, and when clamping mechanism is clamped pipeline, under the Action of Gravity Field of pipeline, long rocking bar 4 diminishes with the included angle A of link supports body 6, and clamping mechanism is firmly grasped pipeline firmly.Spring installation 3 upper ends and link supports body 6 are hinged, lower end and swing pipe main body 1 are hinged, when there is no pipeline Action of Gravity Field, spring installation 3 overcomes after self gravitation, short rocking bar gravity 2, long rocking bar 4 gravity and link supports body 6 gravity, naturally reach the longest, now included angle A increases, and clamping mechanism opening is maximum, conveniently embeds pipeline or unclamps pipeline.
Principle of work and process:
By swing pipe main body 1, be connected with hydraulic excavator, when there is no pipeline Action of Gravity Field, spring installation 3 extends naturally, and clamping mechanism opening opens, and embeds pipeline.Operation hydraulic excavator is mentioned pipeline, under pipeline Action of Gravity Field, spring installation 3 is compressed, and by parallel-crank mechanism, clamping mechanism opening is closed, and clamping pipe firmly, when putting down pipeline, pipeline gravity does not act on, and spring installation 3 extends reset naturally, clamping mechanism opening opens, and unclamps pipeline.
