Description
Technical Field
The utility model belongs to the transportation equipment field in the pit especially relates to a belt bearing roller quick replacement instrument.
Background
The coal mine belt conveyor is an important component of a coal conveying system, and the belt conveyor has the advantages that continuous transportation can be realized under the condition of continuous loading and unloading, so that the belt conveyor can be maintained quickly in daily production, which is an inevitable requirement of production, and in the using process, the belt conveyor is the most common fault due to poor sealing performance of a carrier roller, pollution of thin slurry, corrosion of a carrier roller pipe body and damage of the carrier roller caused by mechanical mechanism design, so that the carrier roller of the belt conveyor becomes one of the most frequently maintained parts and needs to be maintained almost every day.
When the coal mine carrier roller needs to be replaced, due to the tension and the gravity effect of the rubber belt, the two carrier rollers of the rubber belt have to be operated by two persons in a coordinated mode in the installation process, one person uses the crowbar to tilt the rubber belt, and the hanging seat of the carrier roller is installed on the stay bar tensioning pin by one person in a proper way, so that time and labor are wasted, and the maintenance work efficiency is greatly reduced.
Disclosure of Invention
An object of the utility model is to provide a belt bearing roller quick replacement instrument, this instrument can quick replacement belt feeder bearing roller, improves maintenance efficiency.
In order to achieve the above purpose, the technical scheme of the utility model is that: a quick replacement tool for a belt carrier roller comprises a bottom carrier roller installing device and an upper carrier roller installing device,
the bottom carrier roller installing device comprises a transverse frame, a longitudinal rod vertically connected to two ends of the transverse frame, a pry bar and a limiting device, wherein the longitudinal rod is fixedly connected with a plurality of horizontal plates;
the upper carrier roller installing device comprises a groove-shaped frame, wherein one side of the upper end of the groove-shaped frame is fixedly connected with a lifting rod, the other side of the upper end of the groove-shaped frame is obliquely fixed on a frame rod, fixing holes are symmetrically formed in two sides of the groove-shaped frame, and limiting pins are arranged on the symmetrically arranged fixing holes.
The included angle between the rack rod and the groove-shaped rack is 40-60 degrees.
The included angle between the lifting rod and the groove-shaped frame is 90-100 degrees.
The length of the side wall of the mounting frame rod of the groove-shaped frame is greater than that of the mounting lifting rod.
The utility model discloses a belt bearing roller quick replacement instrument can realize single change belt feeder bearing roller purpose, very big improvement work efficiency, and instrument stability is strong, safe and reliable simultaneously.

Detailed Description
Example 1
As shown in fig. 1 to 4, a rapid replacement tool for belt carrier rollers comprises a bottom carrier roller mounting device, an upper carrier roller mounting device,
the bottom carrier roller installing device comprises a transverse frame 11 which is arranged on the upper portion of a belt conveyor frame in a crossing mode, a longitudinal rod 12 vertically connected to two ends of the transverse frame, a pry bar 13 and a limiting device, wherein the longitudinal rod is fixedly connected with a plurality of horizontal plates 14, the horizontal plates are used for placing the pry bar to support a bottom belt, the limiting device is an L-shaped plate 15, one end of the L-shaped plate 15 is fixedly connected to the lower portion of one side of the transverse frame, the L-shaped plate and the transverse frame form a limiting clamping groove, and the limiting clamping groove can clamp a side beam of the belt conveyor,
the upper carrier roller installing device comprises a groove-shaped frame 21, wherein one side of the upper end of the groove-shaped frame 21 is fixedly connected with a lifting rod 22, the included angle between the lifting rod 22 and the groove-shaped frame is 90 degrees, the other side of the upper end of the groove-shaped frame is obliquely fixed to a frame rod 23, the included angle between the frame rod 23 and the groove-shaped frame is 60 degrees, fixing holes are symmetrically formed in two sides of the groove-shaped frame, limiting pins 24 are symmetrically arranged on the fixing holes, and when the groove-shaped frame 21 is matched with a side beam of a belt conveyor frame, the other end of the.
When in use, the bottom carrier roller mounting device or the upper carrier roller mounting device is selected to be used according to the position of the carrier roller which needs to be replaced when damaged,
the bottom carrier roller is replaced, a cross frame of the bottom carrier roller installing device is erected on a belt conveyor frame and clamped on the belt conveyor frame by using a limiting device, then a pry bar is placed on a horizontal plate of a longitudinal beam and penetrates through the lower side of the bottom carrier roller, a maintenance worker lifts the pry bar from the other end and places the pry bar on the horizontal plate on the other side, so that the lower belt is erected, and the maintenance worker replaces the bottom carrier roller;
and replacing the upper carrier roller, placing a rack rod of the upper carrier roller installing device on the lower side of the belt on the belt conveyor, putting one end of the rack rod on a belt conveyor frame, lifting the upper belt by a maintenance worker holding the lifting rod upwards, lifting the upper belt by the rack rod along with the lifting of the trough-shaped frame, and locking the trough-shaped frame on the side beam of the belt conveyor by using a limiting pin when the trough-shaped frame is sleeved on the side beam of the belt conveyor.
Example 2
The length of side of the mounting frame rod of the groove-shaped frame is greater than the length of the mounting lifting rod, and compared with groove-shaped frames with two flush sides, the belt lifted by the frame rod is higher and more convenient to operate when the same height is lifted.
