Description

Arch rib cross brace hoisting device

Technical Field

The utility model belongs to the technical field of the arch bridge construction, a cross brace installation of arch bridge arch rib is related to, concretely relates to hoisting accessory for arch rib cross brace installation.

Background

The arch ribs on two sides of the arch bridge are usually provided with transverse connection called as a transverse support which has structural forms of K-shaped, straight-line-shaped, meter-shaped and the like and is used for ensuring the structural stability of the arch ribs. The cross brace should be installed in time after the closure of the arch rib is completed. The installation of the arch rib cross brace belongs to high-altitude operation, after the installation of the arch rib is completed by adopting a swivel method, the cross brace cannot be installed by adopting a cable crane, the common method is that large hoisting equipment such as an automobile crane is adopted to lift the cross brace to an installation position, and a constructor welds the cross brace and the arch rib at the top of the arch rib, so that the problems that the large equipment is high in cost, and the cross brace is large in amplitude of swing at high altitude during installation, difficult to locate, difficult to construct and long in construction time exist.

Disclosure of Invention

The utility model aims at the above-mentioned problem, provide a simple structure, low in construction cost's arch rib stull hoist device to stability when improving the arch rib installation guarantees that the construction goes on smoothly.

The technical scheme of the utility model as follows:

the utility model provides an arch rib stull hoist device which characterized in that: the device comprises two rhombic supports, wherein each rhombic support comprises a horizontal rod, a vertical rod, a first inclined supporting rod and a second inclined supporting rod which are horizontally arranged, the front end of the horizontal rod is connected with the upper end of the first inclined supporting rod through a bolt, the rear end of the horizontal rod is connected with the upper ends of the vertical rod and the second inclined supporting rod through bolts, the lower ends of the first inclined supporting rod and the vertical rod are connected with the same ear plate through bolts, and the second inclined supporting rod is parallel to the first inclined supporting rod; the front ends of the cross rods of the two rhombic supports are connected with a bearing beam through bolts, and a lifting device is suspended in the middle of the bearing beam; a connecting rod is connected between the vertical rods of the two rhombic supports through bolts, one vertical rod is also connected with the upper end of a third diagonal brace through a bolt, and the lower end of the third diagonal brace inclines towards the outer side of the vertical rod; the lower ends of the second diagonal brace and the third diagonal brace are respectively connected with an ear plate through bolts.

The utility model discloses arch rib after make full use of closure constitutes as the atress carrier the utility model discloses a weight of each component is lighter, can adopt artifical transport to arch rib on, each component assembles into wholly through the bolt scene at the arch rib top, according to the structure of stull, adopts 2 or 4 hoisting accessory to lift by crane an arch rib stull simultaneously, need not the main equipment, and the construction cost is low, and can guarantee the stability of stull hoist and mount process, reduces the construction degree of difficulty, improves the efficiency of construction.

Detailed Description

As shown in fig. 1 and 2, the present invention includes two rhombic supporting frames, each rhombic supporting frame includes a horizontally disposed cross rod 1, a vertical rod 2, a first diagonal brace 3 and a second diagonal brace 4, the front end of the cross rod 1 is connected to the upper end of the first diagonal brace 3 through a bolt, the rear end of the cross rod 1 is connected to the upper ends of the vertical rod 2 and the second diagonal brace 4 through a bolt, the lower ends of the first diagonal brace 3 and the vertical rod 2 are connected to the same ear plate 5 through a bolt, and the second diagonal brace 4 is parallel to the first diagonal brace 3; the front ends of the cross rods 1 of the two rhombic supports are connected with a bearing beam 6 through bolts, and a lifting device 7 is suspended in the middle of the bearing beam; a connecting rod 8 is connected between the vertical rods of the two diamond-shaped supports through a bolt, one vertical rod is further connected with the upper end of a third diagonal brace 9 through a bolt, and the lower end of the third diagonal brace 9 inclines towards the outer side of the vertical rod; the lower ends of the second diagonal brace and the third diagonal brace are respectively connected with lug plates through bolts.

The utility model discloses during the implementation, hoisting accessory 7 can adopt chain block or electric block.

The components of the utility model are separated at ordinary times, and the weight of each component is controlled below 40 kg. The ear plates connected with the lower ends of the inclined support rods and the vertical rods are welded to the top of the arch rib in advance according to the installation positions of the cross braces in the arch rib machining process, after the arch rib rotating construction is completed, constructors carry the rod pieces to climb to the top of the arch rib along the arch rib, the cross brace hoisting device is temporarily assembled by bolts, and the device and the ear plates on the arch rib are connected and fixed. According to the line type of the arch rib, the vertical rod of the rhombic bracket of each hoisting device positioned at the higher part of the arch rib is shorter, so that the bearing beam after the device is installed is in a horizontal state.

As shown in fig. 3, 4 and 5, for the installation of the K-shaped arch rib wale 10, two sets of hoisting devices are respectively installed on the arch ribs 11 on two sides of each wale, 4 sets of devices are respectively connected with 4 corners of the K-shaped wale and are hoisted simultaneously, and for the straight-shaped wale, two sets of devices can be respectively connected with two ends of the wale, so that the stability of the wale in the air can be ensured, and the wale and the arch ribs can be conveniently and smoothly connected.
