Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0019] Such as figure 1 As shown, the counterweight mobile device of the crawler crane of the present invention includes a counterweight, wherein, it includes a beam 1, a rod-shaped telescopic device 2, a sliding device 3 and a counterweight connecting seat 4, the beam 1 is a hexagonal box, and the top surface of the beam 1 One end is provided with a telescopic device connection seat 11, which is connected to one end of the rod-shaped telescopic device 2. The sliding device 3 includes a sliding sleeve 31 and a telescopic device fixing seat 32. The sliding sleeve 31 is horizontally sleeved on the beam 1, and the telescopic device is fixed. Seat 32 is located at the top of sliding sleeve 31, telescopic device fixing seat 32 is connected with the other end of rod-shaped telescopic device 2, the bot...

Abstract

The invention discloses a crawler crane counter weight moving device, which comprises a counter weight, a cross beam, a rod-like telescopic device, a sliding device and a counter weight connecting seat, wherein the cross beam is a hexagonal box body; one end of the top surface of the cross beam is provided with a telescopic device connecting seat; the telescopic device connecting seat is connected with one end of the rod-like telescopic device; the sliding device comprises a sliding sleeve and a telescopic device fixing seat; and the sliding sleeve is transversely sleeved on the cross beam. The device has the beneficial effects that: the counter weight is driven by the sliding device to move forwards and backwards along the cross beam by using stretching of the telescopic device, so that the torque change caused by the counter weight to a hanged load is realized; telescopic sliding of the sliding device along the telescopic device is more flexible by using a crawler rolling device in the sliding device; the contact surface of the cross beam and the sliding device is uniformly stressed; and the counter weight connecting seat is reinforced by using reinforcing ribs, so that the counter weight connecting seat more stably slides along with the sliding device.

Description

technical field [0001] The invention relates to a crawler crane, in particular to a crawler crane counterweight moving device and a crane including the device. Background technique [0002] The counterweight of known crawler cranes is generally fixed, and the specific form is: the counterweight is fixed on the A-frame of the crawler crane, and is connected and fixed with a counterweight stay rope whose one end is fixed on the platform of the crawler crane. Since the counterweight device of this type cannot be moved, the moment of the counterweight of the crawler crane relative to the hoisted object cannot be changed, so that the hoisting load of the crawler crane cannot be changed, and the application range of the crawler crane is limited. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the existing crawler cranes, the present invention provides a crawler crane counterweight moving device and a crane including the device. [0004] The...
