Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-6, a pull rod fixing device for a tower crane comprises an upper cross rod 1, a pull rod support member 2 and a lower cross rod 3 which are horizontally arranged from top to bottom in sequence, wherein the upper cross rod 1 and the lower cross rod 3 are oppositely arranged, two ends of the upper cross rod 1 are respectively and vertically provided with an upper through hole 11, two ends of the lower cross rod 3 are respectively and vertically provided with a lower groove 31, a limiting rod 4 penetrates through the upper through hole 11 and the lower groove 31 at the corresponding end parts of the upper cross rod 1 and the lower cross rod 3, the limiting rod 4 is in threaded fit with the lower groove 31, the limiting rod 4 is in clearance fit with the upper through hole 11, and a limiting nut 41 is sleeved at the upper end part of the limiting rod 4, which is connected with the; the pull rod support piece 2 is arranged on the upper end face of the lower cross rod 3, and the pull rod support piece 2 comprises a plurality of pull rod accommodating grooves 21 which are sequentially arranged.
The lower end face of the lower cross rod 3 is provided with a plurality of supporting seats 5, and the supporting seats 5 play a role in supporting and balancing the pull rod fixing device.
The upper cross rod 1 and the lower cross rod 3 are both round steel, and in one embodiment, the upper cross rod 1 and the lower cross rod 2 are steel pipes with the diameter of 48.3 mm.
The tie bar support 2 is a plurality of interconnected angle bars, in one embodiment, a single angle bar is 50mm by 50 mm.
The flat cushion 42 and the spring cushion 43 are sleeved between the limiting nut 41 and the upper cross rod 1, so that the effect of buffering the tension rod accommodated in the tension rod accommodating groove 21 in the transportation and bumping process can be achieved.
