Abstract

The utility model discloses a trolley for packing emulsion explosives. The trolley comprises a supporting frame with the square cross section, a pair of fixed pulleys are arranged on the upper portion inside the supporting frame, pulley grooves of the fixed pulleys are opposite, the surfaces of the pulley grooves of the fixed pulleys are provided with FeS coatings, a vibration motor is arranged next to the fixed pulleys, universal wheels are arranged at the four corners of the bottom face of the supporting frame, a sleeve is fixed to the upper middle portion of a connecting rod at the bottom of the supporting frame, threads are arranged on the inner wall of the sleeve, a threaded rod is assembled in the sleeve, the lower portion of the threaded rod extends out of the sleeve, the lower end of the threaded rod is in a pointed shape, a disc is horizontally fixed at the position, above the pointed-shaped position, of the threaded rod, and a handle is arranged at the upper end of the threaded rod. Handles for moving the trolley are further arranged at the positions, on the two sides of the upper end of the supporting frame, of an upper connecting plate. The vibration motor enables a rubber pipe to automatically move towards the interior of a blast hole, the disc is in contact with the ground to enable the supporting frame to be stable on the ground, and due to the fact that the FeS coatings are quite small in friction coefficient and abrasion resistant, the service life of the fixed pulleys is prolonged.

Description

A kind of for loading the dolly of emulsion

Technical field

The utility model relates to toward the interior dolly of loading emulsion of blast hole.

Background technology

Along with the development of national economy, nation-building project increases, and needs the place of explosion day by day to increase.On construction ground, conventional emulsion carries out explosion now, emulsion need be filled in blast hole like this, because blast hole is darker, generally by several meters to tens meters, so load emulsion by sebific duct in blast hole.

ZL201220327491.7 discloses a kind of auxiliary means for loading of the mixed loading emulsion explosive car, comprise tripod, fixed pulley is set on tripod, be fixedly installed three sleeve pipes in tripod outside, in three sleeve pipes, cramp bar is set respectively, the processing of cramp bar lower end is pointed; A pair of fixed pulley is set on tripod, and the race of fixed pulley is relative; Pin-and-hole is axially set on sleeve pipe and cramp bar; Top at cramp bar arranges handle; Adopt said structure to load when emulsion to blast hole, the utility model is fixed on to blast hole periphery, the sebific duct of conveying emulsion is positioned on pulley, sebific duct when stretching into or exit in blast hole, not with ground friction, has extended the service life of sebific duct.

Although above-mentioned patent has solved sebific duct and ground friction problem, extend the service life of sebific duct, but find that above-mentioned patent also exists following defect when actual use: when 1 cramp bar lower end pointed is fixed on the ground, owing to being by manual operation, the degree of depth on the pointed insertion ground of cramp bar lower end is more shallow, at sebific duct, when stretching into or exit in blast hole, this device is easily turned on one's side; 2 while inserting big gun hole by sebific duct, because sebific duct and blast hole inwall have friction, needs manually constantly firmly shake conveying rubber pipe; The fine sand of the race surface attachment of 3 fixed pulleys is very fast to the race rate of wear of fixed pulley.

Summary of the invention

For the deficiencies in the prior art part, the utility model aims to provide a kind of for loading the dolly of emulsion, addresses the aforementioned drawbacks guaranteeing.

For reaching above-mentioned purpose, the technical solution adopted in the utility model: a kind of for loading the dolly of emulsion, comprise that a cross section is tetragonal bearing support, at bearing support internal upper part, a pair of fixed pulley is set, the race of fixed pulley is relative, the wheel rooved face of described fixed pulley has FeS coating, the thickness of FeS layer is 0.15-0.2 millimeter, on fixed pulley side, vibrating motor is set, in bearing support bottom surface, four corners position arranges universal wheel, middle part fixed sleeving on the coupling bar of bearing support bottom, internal surface of sleeve pipe is provided with screw thread, in sleeve pipe, be equipped with screw rod, sleeve pipe is stretched out in the bottom of screw rod, the lower end of screw rod is pointed, horizontal fixed disc on the screw rod on pointed top, the upper end of screw rod is provided with handle.

Also be provided with the handle for mobile this device at the upper junction plate of both sides, bearing support upper end.

Adopt technique scheme, this device is shifted onto on blast hole, the sebific duct of carrying emulsion is positioned on fixed pulley, head insert in blast hole, the handle of rotating support frame bottom respectively, insert in soil screw rod lower end, Vibration on Start-up motor, sebific duct moves automatically in blast hole, like this, just in blast hole, loaded emulsion in the past, the filling process smoothness of emulsion, because the processing of screw rod lower end is pointed, be convenient to be fixed on the ground, and along with vibrating motor work, screw rod continues to move down, until disk contacts with ground, so, bearing support is very stable on blast hole.Because the wheel rooved face of fixed pulley arranges after FeS coating, FeS coating friction factor is very little, and wear-resistant, has improved the service life of fixed pulley.

The utility model is simple in structure, and working stability is reliable, can effectively alleviate operation labour intensity.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is Fig. 1 top view;

In accompanying drawing: 1 bearing support 2 upper junction plate 3 lower connecting plate 4 universal wheel 5 sleeve pipe 6 screw rod 7 disk 8 fixed pulley 9 wheel carrier 10 vibrating motor 11 handle 12 handles.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As Fig. 1, shown in Fig. 2, bearing support 1 is frame structure, the cross section of bearing support 1 is square, on the top of bearing support 1, surrounding is provided with upper junction plate 2, at bearing support 1 internal upper part, wheel carrier 9 is set, the outer surface of wheel carrier 9 is connected with upper junction plate 2 inner surfaces by fixed head, be that wheel carrier 9 is fixed on bearing support 1 internal upper part, at a pair of fixed pulley 8 of the interior assembling of wheel carrier 9, the race of fixed pulley 8 is relative, the wheel rooved face of described fixed pulley 8 has FeS coating, the thickness of FeS layer is 0.15-0.2 millimeter, FeS coating has less coefficient of friction, and wear-resisting, can effectively reduce the race surface abrasion speed of fixed pulley 8, vibrating motor 10 is set on the fixed head on fixed pulley 8 sides, and when vibrating motor 10 is worked, wheel carrier 9 also produces vibration, and like this, the sebific duct being placed in fixed pulley 8 races moves down in trend blast hole.

In bearing support 1 Si Ge angular position, bottom surface, universal wheel 4 is set, be convenient to move on-site this device, middle part fixed sleeving 5 on the second line of a couplet fishplate bar 3 of bearing support 1 bottom, sleeve pipe 5 inwalls are provided with screw thread, in sleeve pipe 5, be equipped with screw rod 6, sleeve pipe 5 forms screw pair with screw rod 6, and sleeve pipe 5 is stretched out in the bottom of screw rod 6, the lower end of screw rod 6 is pointed, horizontal fixed disc 7 on the screw rod 6 on pointed top; The upper end of screw rod 6 is also provided with handle 12, by turning handle 12, screw rod 6 is moved up and down, and realizes steady by fixed supporting frame 1; Along with 10 working times of vibrating motor increase, screw rod 6 can continue to insert downwards, and that disk 7 prevents that screw rod 6 from inserting is downwards dark, and when four disks 7 all contact with ground, due to contact-making surface increasing, the steadily of centre of gravity of bearing support 1, when work, does not produce rollover.

Upper junction plate 2 in bearing support 1 both sides, upper end arranges handle 11, and need to move this device time, two people's operating handles 11, one people push away, and another person draws, and can facilitate on-site mobile.
