Problems solved by technology

[0002] The hidden line layout is usually used for cable wiring in oil warehouses, that is, it is necessary to cut out the grooves for embedding line pipes on the wall or on the ground. For grooves with short width and length, manual operation is more convenient, but for grooves with large length and width, manual removal will increase the workload, consume a lot of energy, and the efficiency of groove removal is low; Groove picking also involves cutting both sides of the groove with a marble machine, and then using a hammer and drill to remove the concrete in the middle of the two cutting seams. The cutting can only be completed by applying a large thrust to the marble machine. In the process of use, the saw blade is often loose and the motor is idling.

Embodiment 1

[0023] Such as Figure 1 to Figure 4 As shown, this embodiment includes a housing 1 and a motor 2 installed inside the housing 1. A movable cavity 9 with an open bottom is opened in the middle of the housing 1, and a bevel gear is fixedly arranged on the output end of the motor 2. A4, a rotating shaft 5 is installed in the housing 1, and a saw blade clamping head 7 is installed on one end of the rotating shaft 5, and the saw blade clamping head 7 is placed in the movable cavity 9, and the other end of the rotating shaft 5 is installed with a cone The bevel gear B6 matched with the gear A4; the saw blade clamping head 7 includes a nut 21, a plurality of clamping blocks 16 and movable blocks 19 that are slidably arranged on the rotating shaft 5, and between two adjacent clamping blocks 16 A gap 17 is left, and an annular groove 20 is oppositely arranged on two adjacent clamping blocks 16. The movable block 19 can move freely in the annular groove 20, and the movable block 19 is ...

Embodiment 2

[0026] Such as figure 1 and figure 2As shown, in this embodiment, on the basis of Embodiment 1, a rear armrest 14 is installed at one end of the housing 1, and two supporting plates 15 arranged in parallel are installed on the other end of the housing 1, and the two supporting plates 15 is connected by front armrest 13. When in use, the operator holds the movable handle and the fixed handle respectively to cooperate with a plurality of rollers 10 to push the movement of the housing 1, wherein the movable handle is installed between two support plates 15, when the movable handle is pressed down, the saw blade is cutting the wall Larger vibrations will be generated when the operator is in the body. Through the buffering effect of the two armrests, the impact of vibration on the hands of the operator is greatly reduced, further reducing the workload of the operator.

[0027] It also includes a fixed cylinder 3 installed on the housing 1 , and the rotating shaft 5 is rotatably ...

Embodiment 3

[0029] Such as figure 1 and figure 2 As shown, this embodiment is based on Embodiment 1, and the movable cavity 9 is provided with a through hole 8 communicating with the outside. Since the saw blade rotates at a high speed when cutting, there will be continuous friction with the wall or the ground, which will generate a large amount of heat. The closed bottom end of the movable cavity 9 is provided with a through hole 8 communicating with the outside world. Depending on the structure of the body or the ground, the through hole 8 can be connected with a water pipe or a vacuum cleaner. When the temperature of the saw blade increases or the amount of dust in the movable cavity 9 increases, cooling water is injected or drawn out of the movable cavity 9. The accumulation of dust can not only ensure the normal use of the present invention, but also avoid a large amount of dust from polluting the operating environment.

Abstract

The invention discloses a multi-blade trench cutting machine. The multi-blade trench cutting machine comprises a shell and a motor, a movable chamber with an open bottom is formed in the middle of the shell, a saw blade clamping head is arranged in the movable chamber and comprises a nut, a plurality of clamping blocks and movable blocks, a bevel gear B matched with a bevel gear A is mounted at the other end of a rotating shaft, the clamping blocks are arranged on the rotating shaft slidably, a gap is reserved between each two adjacent clamping blocks, annular grooves are formed in each two adjacent clamping blocks oppositely, the movable blocks are capable of moving in the annular grooves freely and connected with the bottoms of the annular grooves through springs, a thread is formed in the outer wall at the end of the rotating shaft, and the nut is in thread fit with the rotating shaft. The multi-blade trench cutting machine has the advantages that since the clamping blocks and the movable blocks are used for clamping and fixing saw blades, when the saw blades vibrate, the springs at the bottoms of the annular grooves restore by means of elastic deformation and are capable of counteracting a stress effect produced by vibration effectively, idling of the rotating shaft is avoided and trench cutting efficiency is improved while stable rotation of the saw blades is guaranteed.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a multi-blade slotting machine. Background technique [0002] The hidden line layout is usually used for cable wiring in oil warehouses, that is, it is necessary to cut out the grooves for embedding line pipes on the wall or on the ground. For grooves with short width and length, manual operation is more convenient, but for grooves with large length and width, manual removal will increase the workload, consume a lot of energy, and the efficiency of groove removal is low; Groove picking also involves cutting both sides of the groove with a marble machine, and then using a hammer and drill to remove the concrete in the middle of the two cutting seams. Only when a large thrust is applied to the marble machine can the cutting be completed. In the process of use, the saw blade often becomes loose and the motor runs idly. Contents of the invention [0003] The purpose of the pres...
