Technical Field
The invention relates to the technical field of escalator assembly, in particular to an assembly fixture for an escalator halter.
Background
Most escalator manufacturers currently use conventional methods when installing stainless steel cages. Firstly, a central line is punched on a truss, and then, the two side caged heads are respectively hung on truss art weldments. The distance between the tap and the central line, the distance between the tap and the large angle steel and the distance between the tap and the truss are measured for a plurality of times to respectively and repeatedly adjust the tap. After the three sizes of the two-side halters are respectively adjusted, the relative positions of the two halters still need to be adjusted because the relative positions of the two halters still have deviation. The whole assembly process needs repeated measurement and debugging, and the working strength and the difficulty are both great.
In view of the inconvenience of the above operation modes, some assembling tools and auxiliary tools for escalator halts gradually appear in an escalator manufacturing workshop, and chinese patent specification CN104722996B discloses a folding and positioning device for an upper end of an escalator, which is used for folding and positioning a driving assembly and two side plates at the upper end of the escalator, and comprises: the workbench comprises a transverse table top and a longitudinal table top, a left fixed support frame, a right fixed support frame, a front fixed support frame and a rear fixed support frame, a first upper caliper and a first lower caliper which are connected to the front fixed support frame, a second upper caliper and a second lower caliper which are connected to the rear fixed support frame, side plate supporting pieces which are respectively connected to side plates at two sides, and driving sprocket supporting pieces which are respectively connected to the left fixed support frame and the right fixed support frame; positioning support grooves for accommodating side plate support pieces are respectively formed in the left fixed support frame and the right fixed support frame, and the upper parts of the driving sprocket support pieces are matched with tooth grooves on driving sprockets in the driving assembly.

When the escalator halters 8 and 9 with certain specifications are assembled for the first time, as the left limiting plate 2 and the right limiting plate 3 are fixedly connected on the horizontal support 1, after the horizontal support 1 is adjusted by using tools such as a horizontal ruler, the positions of the left limiting plate 2 and the right limiting plate 3 are determined, and the left working plate 4, the left rear working plate 6, the right working plate 5 and the right rear working plate 10 can be used as a reference system for adjusting the left working plate 4, the left rear working plate 6 and the right working plate 5. As shown in fig. 2, the two-side escalator bezels 8 and 9 are respectively placed on the left bottom plate 210 and the right bottom plate 310, then the threaded pins 740 at the two ends of the positioning and hoisting assembly 7 are inserted into the center holes of the two-side escalator bezels 8 and 9, in order to reduce the shearing force of the two-side escalator bezels 8 and 9 on the left bottom plate 210 and the right bottom plate 310, which is huge in weight, the positioning and hoisting assembly 7 is provided with a base 770, and the base 770 is supported at the bottoms of the two-side escalator bezels 8 and 9 to share the huge gravity suffered by the left bottom plate 210 and the right bottom plate 310 and avoid the deformation of the left limiting plate 2 and the right limiting plate 3. Taking debugging of the left escalator halter 8 as an example, when the position of the left escalator halter 8 is debugged, 4 left bolts 231 fix the left side plate 230 and the left working plate 4 at the same horizontal height, and the relative position between the left working plate 4 and the left side plate 230 can be manually adjusted by pushing and pulling the left bolts 231 and then fixing the left bolts with left nuts 232; the left and right plates 220 and the left rear working plate 6 are fixed at the same horizontal height by 4 left rear bolts 221, and the relative positions between the left rear working plate 6 and the left rear plate 220 can be manually adjusted by pushing and pulling the left rear bolts 221 and then fixing with left rear nuts 222. The adjustment is completed, the positioning hoisting assembly 7 is fixedly connected with the left escalator halter 8, at this time, in order to eliminate the influence on the left escalator halter 8 in the process of connecting the installation flange 760, the left trimming screw 233 and the left rear trimming screw 223 are adjusted, the left trimming screw 233 is propped against the left working plate 4, the thrust of the left trimming screw 233 to the left working plate 4 is trimmed, the left rear working plate 6 is propped against the left right trimming screw 223, and the thrust of the left rear trimming screw 233 to the left and right working plate 6 is trimmed, so that the fine deviation generated in the process of connecting the installation flange 760 can be eliminated.
Similarly, the positioning of the right escalator halter 9 is consistent with the principle and the operation process of the left escalator halter 8. After the two-side escalator halters 8 and 9 are debugged on the assembling tool, the two-side escalator halters 8 and 9 can be assembled accurately, and the relative positions of the two-side escalator halters 8 and 9 are very accurate.
Positioning during debugging is mainly achieved through the first sight 110, the second sight 120 and the third sight 720. The first sight 110, the second sight 120 and the third sight 720 are long strips with opposite V-shaped notches at two ends. Of course, the V-shaped notch may be designed into other structures, such as a firearm aiming device structure, and an optical aiming device may be used instead of the mechanical structures of the first aiming device 110, the second aiming device 120, and the third aiming device 720. The first sight 110 and the second sight 120 are always perpendicular to the horizontal connecting rod of the first sight 110 and the second sight 120 on the horizontal support 1, and the third sight 720 is always perpendicular to the horizontal rod 710. As shown in fig. 3, in the debugging process, the first sight 110, the second sight 120 and the third sight 720 are horizontally moved and adjusted according to the situation, so long as the coincidence of the straight line L1 formed by connecting the V-shaped notches of the first sight 110 and the second sight 120 and the straight line L2 formed by connecting the V-shaped notches at the two ends of the third sight 720 is ensured, the positioning accuracy of the escalator cages 8 and 9 at the two sides can be ensured.
After the assembly is completed, the escalator heads 8 and 9 on the two sides are hoisted to the escalator truss from the assembly fixture. Lifting lugs 730 are connected to the horizontal rods 710 of the positioning lifting assembly 7, and lifting operations can be easily completed by means of ropes penetrating through the lifting lugs 730. Because the positioning and hoisting assembly 7 is tightly and firmly connected with the escalator claps 8 and 9 on the two sides, the relative positions of the escalator claps 8 and 9 on the two sides are always consistent in the hoisting process, and the escalator claps 8 and 9 on the two sides are lifted and separated from the assembly tool and then put into the escalator truss for subsequent assembly and welding and other procedures.
After the first assembly work is completed, the assembly fixture can be unfolded for the next assembly work without large-scale debugging again. The subsequent assembly operation only needs to combine the aiming positioning of the first aiming device 110, the second aiming device 120 and the third aiming device 720 through the fine adjusting screw, and the high precision and consistency of each assembly operation can be ensured through small-range adjustment. The assembling tool is high in efficiency of assembling the escalator halter, and time-saving and labor-saving.
The present invention is not limited to the above-described embodiments, but, if various modifications or variations of the present invention are not departing from the spirit and scope of the present invention, the present invention is intended to include such modifications and variations as fall within the scope of the claims and the equivalents thereof.
