Abstract

The invention discloses a spreader having an adjustable balanced beam, comprising a beam; a lower end of the beam is provided with a plurality of positioning troughs; the beam is connected with a balancing seat which is provided with a rolling mechanism in contact with the beam and a positioning shaft matching with the positioning troughs respectively. The balancing seat consist of a front and a back board which are arranged at the front and back ends of the beam; the positioning shaft passes through the front and back boards of the balancing seat; one end of the positioning shaft is providedwith a handle, and the other end is provided with a fixed pin; the middle part of the positioning shaft is provided with a flute; the front board of the balancing seat is provided with a left and a right handle stop block. The rolling mechanism comprises a connecting shaft which connects the front and back boards of the balancing seat and a roller equipped on the connecting shaft. As the beam ofthe spreader provided by the invention is provided with the balancing seat which can move along the beam, heavy objects can be lifted easily, rapidly, safely and reliably by adjusting the position relationship between the balancing seat and the beam according to the gravity offset of the lifted heavy object.

Description

Suspender with adjustable balanced type transverse beam

Technical field

The present invention relates to the lifting appliance in a kind of hanging device, relate in particular to a kind of cross beam type hoisting appliance.

Background technology

In structure steel fabrication or equipment installation, the suspension centre span of some parts is bigger, causes the steel rope angle also excessive, at present, normally adopts the crossbeam suspender to solve this problem.Have in the suspender process of crossbeam in use; also run into situation asymmetric by the shape of lifting part and that centre-of gravity shift is excessive through regular meeting; therefore occur tilting after tending to cause parts to sling; brought hidden danger for the safety lifting; if it is serious that lifting part tilts, can cause to lift at all.This has brought very big difficulty for lifting work, simultaneously, and the personal safety that threatens the operator that also can be serious.Conventional solution one is the steel rope that utilizes length different; The 2nd, adopt the suspender that has beam structure as shown in Figure 1, the crossbeam two ends of this suspender are disposed with a plurality of knock holees 21 that are used to install steel rope along crossbeam length, when using this suspender, according to by the side-play amount of lifting object center of gravity, with the steel rope U type ring 22 of laying particular stress on a side be fixed on a comparatively approaching knock hole 21 of hook on hole 20 in, make crossbeam both sides steel rope attachment point difference, that is, guarantee in the hoisting process by the balance of lifting object by the adjustment of lifting by crane the arm of force.Use this suspender hoisting heavy, may screw again after determining to use which position of positioning hole owing to the unusual bolt pin that before each the use, all needs to dismantle steel rope U type ring 22 of weight eccentric position.If can not realize once finding accurately the center of gravity of weight, may also need to repeat or repeatedly repeat again above-mentioned steps.The weak point of utilizing above-mentioned prior art to have the suspender lifting centre-of gravity shift weight of beam structure is owing to can not determine the center of gravity of lifted weight thing effectively, accurately, once, therefore bring very big inconvenience to operation, and can not guarantee the lifting of finishing of safety and steady.

Summary of the invention

Operation inconvenience when lifting the centre-of gravity shift weight in order to overcome above-mentioned prior art suspender, safe and reliable inadequately defective the invention provides a kind of suspender with adjustable balanced type transverse beam.

In order to solve the problems of the technologies described above, the present invention has the technical scheme that the suspender of adjustable balanced type transverse beam is achieved: comprise crossbeam, the lower end of described crossbeam is provided with a plurality of positioning grooves, be connected with the balance seat on the described crossbeam, be respectively arranged with rolling mechanism that contacts with crossbeam and the fix shaft that cooperates with described positioning groove on the described balance seat; Described balance seat is made up of the front and rear panel that is positioned at the crossbeam rear and front end, and described fix shaft passes balance seat front and rear panel, and the one end is provided with handle, and the other end is provided with set pin; The middle part of described fix shaft is provided with groove, two retaining lever catch pieces about the header board of described balance seat is provided with.Described rolling mechanism is made of adapter shaft that connects balance seat front and rear panel and the roller that is arranged on the adapter shaft.

Compared with prior art, the beneficial effect that the present invention had is: because crossbeam is provided with the balance seat that can move along crossbeam, therefore, can be according to by the barycentre offset of hoisting heavy, concern by the position of adjusting between balance seat and the crossbeam, thereby can lift weight easily, fast, safely, reliably.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.

Shown in Fig. 2-1 and Fig. 2-2, the suspender that the present invention has adjustable balanced type transverse beam comprises crossbeam 10, the lower end of described crossbeam 10 is provided with a plurality of positioning grooves 11, be connected with balance seat 30 on the described crossbeam 10, be respectively arranged with rolling mechanism 40 that contacts with crossbeam 10 and the fix shaft 31 that cooperates with described positioning groove 11 on the described balance seat 30.Described balance seat 30 is made up of header board 32 that is positioned at crossbeam 10 rear and front ends and back plate 33, described fix shaft 31 passes the forward and backward

plate

32 and 33 of balance seat, and fix by packing ring and nut by packing ring and spring cotter are fixing, fix shaft 31 can rotate in axis hole, but can not come off.One end of described fix shaft 31 is provided with handle 34, and the other end is provided with set pin 35; Shown in Fig. 2-3 and Fig. 2-4, the centre of fix shaft 31 has a groove 36 slightly wideer than crossbeam 10, two retaining lever catch pieces 37 about described balance seat header board 32 is provided with, remove when the handle 34 of fix shaft 31 and to forward to when contacting with left side handle block 37, the groove 36 of fix shaft 31 is in open mode just.At this moment the edge, lower end of crossbeam 10 can freely pass through in groove 36.Because edge, crossbeam 10 lower end is provided with a plurality of positioning grooves 11, after fix shaft 31 moves on on the required positioning groove 11, handle 34 is removed on the handle block that forwards opposite side to again.At this moment, the balance seat is in locking state in crossbeam, can carry out lifting work.Shown in Fig. 2-5, described rolling mechanism 40 constitutes by connecting forward and backward plate 32 of balance seat and 33 adapter shaft 41 and the roller 42 that is arranged on the adapter shaft 41.Balance seat 30 is to be enclosed within on the crossbeam 10, and carries out moving easily on crossbeam by the drive of the roller on rolling mechanism 40 adapter shafts 41 balance seat 30.

Although in conjunction with the accompanying drawings the present invention has been carried out foregoing description; but the present invention is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under enlightenment of the present invention; under the situation that does not break away from aim of the present invention, can also make a lot of distortion, these all belong to the row of protection of the present invention.
