Embodiment 1

[0044] The tensioning mechanism provided in this embodiment includes: a mounting frame 1 , a driving member 2 and a tensioning cam 3 .

[0045] In the embodiment of the present application, the mounting frame 1 has a through slot 4 suitable for sliding and a guide slot 5 communicating with the through slot 4 .

[0046] Such as figure 1 , figure 2 As shown, the mounting frame 1 is a frame structure formed by plate welding, the bottom surface of the mounting frame 1 is suitable for installation and fixing, and an accommodating cavity is formed inside the mounting frame 1; Toward the guide end of the part to be tensioned, the guide end has a through groove 4 with an opening suitable for facing the part to be tensioned; the guide end has a guide groove 5, and the guide groove 5 communicates with the installation frame 1 between the accommodating cavity and the through groove 4. Wherein, a guide wheel 16 is slidably disposed in the through groove 4 .

Embodiment approach 2

[0056] Wherein, the locking assembly can electrically lock the tensioning cam 3 , and can be driven and locked by a driving means such as a motor or an electric cylinder. Specific embodiment one: the locking member is a first gear that is concentrically sleeved on the first rotating member 6, and the mounting frame has a second gear that is rotated, and the second gear is connected to the The first gear is meshed and connected; the second gear is driven by a motor, and the second gear meshes and drives the first gear to realize positioning and locking of the tensioning cam 3 . Specific embodiment two: the first rotating member 6 can be directly connected to the output end of the motor, and the rotation of the first rotating member 6 can be realized through the rotation of the motor, and the position locking of the first rotating member 6 can also be controlled at the same time .

Embodiment approach 1

[0057] The locking assembly can perform mechanical locking on the tensioning cam 3, and perform locking and positioning by manual operation. Concrete embodiment one: a positioning plate is concentrically sleeved on the first rotating member 6, and a plurality of positioning holes are opened on the positioning plate, and locking holes corresponding to the positioning holes are provided on the mounting frame; The positioning and locking of the tensioning cam 3 are realized by passing through the positioning hole and the locking hole in sequence by screws or pins to realize the position limitation of the first rotating member 6 .

[0058] When the tensioning cam 3 rotates to a preset position, the locking assembly can position and lock the tensioning cam 3 through a locking member, preventing the tensioning cam 3 from rotating in reverse, so that the tensioning cam 3 Press against the part to be tensioned.

[0059] In a preferred embodiment of the present application, the lockin...

Abstract

The invention provides a tensioning mechanism and engineering mechanical equipment, and belongs to the technical field of engineering mechanical equipment, and the tensioning mechanism comprises a mounting frame, a tensioning device, a tensioning device, a tensioning device, a tensioning device and a tensioning device, and the mounting frame is provided with a through groove suitable for sliding and a guide groove communicating with the through groove; the driving part is arranged in the guide groove in a sliding mode, and is suitable for penetrating through the guide groove and abutting against a part to be tensioned in a contact mode; and the tensioning cam is eccentrically and rotationally connected to the mounting frame through a first rotating part, and the tensioning cam is in contact with and abuts against the driving part. According to the tensioning cam, the driving part is pushed to slide along the guide groove through eccentric rotation, and the driving part directly or indirectly abuts against the to-be-tensioned part to achieve tensioning of the to-be-tensioned part; according to the tensioning structure, the driving part is pushed to act through rotation of the tensioning cam, the mode that oil is injected into the oil cylinder to drive the piston to stretch out and draw back is replaced, the structure is simple, cost is low, and the influence on other parts caused by oil leakage is avoided.

Description

technical field [0001] The invention relates to the technical field of construction machinery equipment, in particular to a tensioning mechanism and construction machinery equipment. Background technique [0002] After a period of use of the excavator, due to the wear of the rail chain and the driving wheel, the track shoe or the track chain pitch is elongated, so that the track cannot maintain a certain tension and deflects downwards, and it is easy to grind the track frame, derail and Phenomena such as chain drop, causing the crawler walking device to not work normally. [0003] At present, the tensioning device is in the form of an oil cylinder piston telescoping, and the tensioning of the track is realized by driving the driving wheel to move by the piston. When tensioning, it is necessary to inject butter into the oil cylinder, which is not only complicated in structure and high in cost, but also prone to oil leakage and pollution of other parts, and the oiling process...
