Abstract

The utility model discloses an assembly-type adjustable gantry, aiming to provide an assembly-type adjustable gantry with convenient transportation, simple structure and adjustable beam height. The gantry comprises pillars on both sides and a beam movably connected with the top between the two pillars, wherein each pillar is connected with a bottom frame at the bottom thereof; each bottom frame has movable rollers arranged on the bottom in at least two positions; and the beam is generally made of I-steel. The utility model is characterized in that the beam includes at least two segments connected with each other, and the connection is achieved respectively by fixing closed connection boards on the upper and lower surfaces of the connection ends of the two beam segments, forming connection holes on the connection board, and respectively fixing the closed connection boards through screw thread connectors. With the utility model, the beam and the pillars can be detached in segments, which can facilitate transportation and greatly reduce the transportation cost. The height of the beam can be adjusted by adjusting the relative positions of the pin holes and the adjusting holes according to requirement during use, and the utility model is easy to manufacture and convenient to assemble.

Description

The adjustable portal frame of build-up type

Technical field

The utility model relates to weight-lifting equipment, particularly the portal frame in the small-sized gantry crane.

Background technology

The portal crane that some are small-sized has the portal frame of door case type, and portal frame has the column on both sides, and the top between two columns is connected with crossbeam, forms portal frame.Shifting roller is equipped with in the bottom of portal frame, and crossbeam generally is " worker " Zee bar steel Z, on be connected with hoisting device, as hoist crane etc., hoisting device can move along crossbeam.During lifting, the mobile gantry frame makes crossbeam above a weight.And the hoisting device on the mobile gantry frame, make the lifting hook of hoisting device aim at substantially with weight and be connected, hoisting heavy then, after requiring height, the mobile gantry frame has been realized the transfer of weight.The transportation of portal crane often is divided into portal frame three parts, two root posts and a crossbeam for convenience.But nonetheless, the length of column and crossbeam is still very long, results in hand cramps to transportation, and the cost of transportation is also very big.And the crossbeam of general portal crane is fixed apart from ground-surface height, and this gives to use and also brings many inconvenience.

The utility model content

The utility model provides a kind of convenient transportation, the adjustable portal frame of build-up type simple in structure, the crossbeam height-adjustable.

In order to satisfy above-mentioned requirements, the utility model is achieved through the following technical solutions: the column that includes both sides, top movable between two columns is connected with crossbeam, form portal frame, the bottom of each column is connected with underframe, each underframe has at least the bottom at two places that shifting roller is housed, crossbeam generally is " worker " Zee bar steel Z, it is characterized in that crossbeam has at least two sections butt joints to form, described butt joint be respectively on two sections crossbeam butt ends and below be fixed with involutory connecting panel, on connecting panel, be shaped on connecting bore, involutory connecting panel be separately fixed at together by threaded connector.

Described each column has two sections to be socketed to form, and promptly wherein is shaped on sleeve pipe on one section, and another section is plugged in the sleeve pipe, and has pin fixed to fastening.The top of described underframe is shaped on adjustable pipe, be shaped on pin-and-hole on the adjustable pipe, column is inserted in the adjustable pipe, is shaped on the corresponding a plurality of adjustment holes that distribute up and down with pin-and-hole on the column, column moves up and down in adjustable pipe, and is inserted the position of vertical columns in pin-and-hole and the adjustment hole by latch.

The adjustable portal frame of build-up type according to the such scheme manufacturing, a crossbeam can be divided into two at least, each column also can be taken apart with being divided into two, this brings many facilities to transportation, also can reduce the expense of transportation greatly, in use can regulate the relative position of pin-and-hole and adjustment hole as requested, the height and position of crossbeam is adjusted, and easy to manufacture, easy to assembly.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1 to Fig. 5 is the structural representation of the adjustable portal frame of build-up type.It includes the column 1 on both sides as seen from the figure, top between two columns 1 is connected with crossbeam 3 by bolt 2, form portal frame, described crossbeam 3 is " worker " Zee bar steel Zs, there are two sections butt joints to form, it be on two sections crossbeam 3 butt ends and below be welded with involutory connecting panel 4, on connecting panel 4, be shaped on connecting bore 5, by threaded connector 6 involutory connecting panel 4 is separately fixed at together.Be combined into the described crossbeam 3 of detouchable.Each column 1 has two sections to be socketed to form, and wherein is shaped on sleeve pipe 8 on the end of epimere 7, and the end of hypomere 9 is plugged in the sleeve pipe 8, and fasten by

bolt

10 and 11 pairs on nut fixed.The hypomere 9 of column 1 is movably connected with underframe 12, and underframe 12 is ladder frames, ladder frame go to the bottom 13 greater than upper base 14, go to the bottom and two groups of shifting rollers 15 be housed on 13, all go to the bottom 13, upper base 14 and waist 16 all link together by threaded connector 17.Be welded with adjustable pipe 18 on the upper base 14 of underframe 12, for stable, upper base 14 is by the two bar shaped materials up and down of flat shape and adjustable pipe 18 welding, be shaped on two pin-and-holes 19 on the adjustable pipe 18, the hypomere 9 of column 1 is inserted in the adjustable pipe 18, be shaped on the hypomere 9 and the pin-and-hole 19 corresponding a plurality of adjustment holes 20 that distribute up and down, column 1 moves up and down in adjustable pipe 18, and is inserted the position of vertical columns 1 in pin-and-holes 19 and the adjustment hole 20 by latch 21.The adjusting of column 1 height can be fixed with handle 22 in the lower end of hypomere 9 for convenience.For improving the weld strength of connecting panel 4 and crossbeam 3, scolder has the support angle 23 of reinforcement respectively between them.
