Description
Technical Field
The utility model relates to a prefabricated box culvert lifting device, concretely relates to box culvert hoist that is used for on-spot upset hoist and mount of prefabricated box culvert.
Background
In the engineering construction process, a man box culvert is required to be arranged in a roadbed when the road passes through an original road; in order to ensure the construction quality and shorten the construction period, the prefabricated box culvert is popularized; because the section size of the box culvert is large, the box culvert needs to be prefabricated in sections and hoisted and installed in batches so as to ensure the construction safety and the installation accuracy.
After the box culvert is prefabricated, the box culvert needs to be transported to a construction site for hoisting, overturning and mounting; in the prior art, the box culvert is overturned and installed by adopting an overturning trolley to be matched with a pure rigid lifting appliance for lifting, the overturning and lifting method is high in cost, and the lifting appliance is easy to fatigue and damage.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a box culvert hoist for prefabricated box culvert upset hoist and mount makes it solve the on-the-spot upset difficulty of prefabricated box culvert, the complicated scheduling problem of installation machines, simplifies and contains the section upset hoist and mount machines, improves the efficiency of construction.
The utility model aims at realizing through the following technical scheme:
a reversible box culvert lifting appliance for on-site installation of a box culvert is provided with a lifting appliance beam; the lifting appliance beam is a structure formed by welding I-shaped steel and a steel plate; two ends of the lifting appliance beam in the length direction are respectively provided with a group of upper lifting lugs; the upper lifting lugs are respectively connected with hoisting equipment through flexible chain links; the lower part of the lifting appliance beam is provided with a lower lifting lug; the lower lifting lugs are two groups of lifting lugs positioned at the lower parts of the two ends of the length direction of the lifting appliance beam; each group of lower lifting lugs is two lifting lugs symmetrically arranged by using the middle point of the beam; each lower lifting lug is connected with an insertion type steel bar for inserting into a box culvert piece lifting hole through a flexible chain; the two groups of four inserted steel bars form a car unloading mechanism for horizontally grabbing the box culvert; and the two groups of inserted steel bars form a movable hoisting mechanism for hoisting and moving the box culvert.
The group of upper lifting lugs is two which are arranged in bilateral symmetry.
The utility model provides a box culvert hoist for on-spot upset hoist and mount of prefabricated box culvert, the chain that excels in that four strands have bayonet hoist hole rod iron is connected through a set of lower lug of crossbeam lower part during the use carries out the flat of box culvert festival to lie and snatchs the unloading, lifts by crane and removes two strands of lower part chains after falling to the ground, only uses two strands of chains to insert two hoist holes of containing festival heteropleural coaxial line and contain 90 upsets of festival upright, lifts by crane the installation crossbeam lower part and only adopts two strands of chains to hoist to remove and contain the festival equally. The novel device has strong applicability, and effectively improves the construction efficiency of box culvert on-site overturning installation.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following description of the embodiments of the present invention is provided for clear and complete description of the technical solutions. This embodiment is a part of the present invention, and not all embodiments. Based on the embodiments in the present invention, other embodiments obtained by a person of ordinary skill in the art without creative work all belong to the protection scope of the present invention.
As shown in fig. 1, the box culvert spreader for box culvert field installation is provided with a spreader beam 1; the lifting appliance beam 1 is a structure formed by welding I-shaped steel and a steel plate; two ends of the lifting appliance beam 1 in the length direction are respectively provided with a group of upper lifting lugs 2; the upper lifting lug 2 is connected with hoisting equipment through a flexible chain 6; the lower part of the lifting appliance beam 1 is provided with a lower lifting lug 3; the lower lifting lugs 3 are two groups of lifting lugs positioned at the lower parts of the two ends of the length direction of the lifting appliance beam; two lower lifting lugs 3 are arranged in each group; each lower lifting lug is connected with an inserted steel bar 7 inserted into a box culvert piece lifting hole through a flexible chain; the two groups of four inserted steel bars form a car unloading mechanism for horizontally grabbing the box culvert; and the two groups of inserted steel bars form a movable hoisting mechanism for hoisting and moving the box culvert.
As shown in fig. 2, the upper lifting lugs are triangular steel plates welded with the main beam, and each upper lifting lug is reinforced by an upper lifting lug reinforcing plate 4; as shown in fig. 3, a lower lifting lug reinforcing plate 5 is transversely welded on each of the left side and the right side of the lower lifting lug, the lower lifting lug reinforcing plates are welded in a manner of being tightly attached to the lifting lugs, and the width of the steel plate is consistent with that of the cross beam; the upper lifting lug, the lower lifting lug and the reinforcing plate are firmly welded with the cross beam and the lifting lugs, and the steel bar at the bottom of the chain is flexibly connected with the chain through the butterfly buckle. The I-steel type used by the crossbeam, the upper and lower lifting lug positions arranged on the crossbeam and the upper and lower chain type for hoisting (steel bar containing hoisting jacks) are selected according to the size and weight of the hung culvert section, the upper lifting lug is connected with hoisting equipment through two high-strength chain lines, and the lower lifting lug is connected with the culvert section through the high-strength chain line.
