Roadway advanced self-moving type supporting hoisting machine

Abstract

The invention discloses a roadway advanced self-moving type supporting hoisting machine and relates to coal mine underground hoisting supporting equipment. The roadway advanced self-moving type supporting hoisting machine is used for hoisting, moving and placing other equipment and materials in a roadway advanced supporting system or under a well. The roadway advanced self-moving type supporting hoisting machine comprises a hoisting support, an anchoring support, push-and-pull jacks and a guide limiting rod, wherein the push-and-pull jacks are mounted on the left side and the right side of the space between a base of the hoisting support and a base of the anchoring support, and the guide limiting rod is mounted behind the base of the hoisting support. In the hoisting process, a top beam of the hoisting support is used for supporting a top plate, protects the top plate and meanwhile is a counterbalance to a hoisting mechanism, and thus hoisting reliability is improved. The hoisting mechanism can rotate and swing up and down, and the movement range of the hoisting mechanism is widened through a telescopic jib. The anchoring support and the hoisting support are fulcrums for each other and can automatically move forwards or backwards, the accuracy of movement paths of the anchoring support and the hoisting support is improved through the guide limiting rod, and the support movement capacity and the flexibility in the movement process are enhanced through the two push-and-pull jacks. The roadway advanced self-moving type supporting hoisting machine has high hoisting capacity, good maneuverability and high reliability, and is used for hoisting the equipment and meanwhile safely supporting a roadway.

Description

technical field [0001] The invention relates to a coal mine underground hoisting support equipment, in particular to a roadway advance self-moving support hoisting machine. Background technique [0002] With the continuous improvement of the level of coal mining technology, the underground fully mechanized mining equipment has also been continuously developed. At present, in the advance support of coal mine roadways, there are mainly wooden pile supports, single hydraulic prop supports, and advance supports that move in groups as a whole. For roadways with complex conditions, these support methods cannot well meet the support requirements, and the non-repeated support advanced support system with strong support capacity and good effect depends on lifting, handling or winch pulling. In the research, but no matter what kind of advanced support system without repeated support, it is necessary to lift the tail advanced support to the middle of the roadway, and then lift the adva...

Problems solved by technology

[0002] With the continuous improvement of the level of coal mining technology, the underground fully mechanized mining equipment has also been continuously developed. At present, in the advance support of coal mine roadways, there are mainly wooden pile supports, single hydraulic prop supports, and advance supports that move in groups as a whole. For roadways with complex conditions, these support methods cannot well meet the support requirements, and the non-repeated support advanced support system with strong support capacity and good effect depends on lifting, handling or winch pulling. In the research, but no matter what kind of advanced support system without repeated support, it is necessary to lift the tail advanced support to the middle of the roadway, and then lift the advanced support moved to the head and place it on both sides of the roadway. For the hoisting and moving of large equipment or materials such as advanced brackets, ordinary hoisting anchors and electric hoists have the disadvantages of small hoisting weight, inconvenient movement, and poor reliability, which cannot meet the requirements. , high reliability lifting device to complete the work
