Problems solved by technology

[0004] But at present, when the above-mentioned cement mortar added with gelatinous material is used to pour the roof concrete cracks, since most of the cracks have narrow and small openings, their direction is not linear, but irregular in a serpentine shape. It is difficult for pouring equipment to pour according to the direction of cracks, and it is prone to uneven pouring

Embodiment 1

[0030] Embodiment 1: A hand-held roof crack repair machine, the frame is composed of a chassis 1 and an armrest frame 2 arranged at the rear end of the chassis 1 and tilted backward, an angle adjustment mechanism is arranged between the armrest frame 2 and the chassis 1, The inclination angle of the armrest frame 2 can be adjusted. The upper part of the armrest frame 2 is provided with a collection box for storing cables and placing other tools. The lower part of the armrest frame 2 is provided with a motor as the power unit 6. The height of the front end of the chassis 1 from the ground is smaller than that of the rear end of the chassis 1. The height from the ground, the bottom of the chassis 1 is provided with a walking wheel 5, wherein the front end is a universal wheel, the rear end is a driving wheel, and the driving wheel is driven by the above-mentioned power device 6, between the universal wheel and the driving wheel from front to back A slotted plate 3 for widening th...

Embodiment 2

[0033] Embodiment 2: A hand-held roof crack repairing machine. On the basis of the structure of Embodiment 1, a leveling device is arranged behind the pouring pipe 403, and the leveling device includes a height that is fixedly connected to the chassis 1. The adjusting rod 9 and the scraper 8 arranged at the bottom of the height adjusting rod 9, the scraper 8 is composed of an inclined part and a horizontal part, the front end of the inclined part is high, the rear end is low, the horizontal part is connected with the rear end of the inclined part, and then the The poured repair material is scraped off at the opening of the crack, and the height of the scraper 8 from the ground is adjusted by the height adjustment rod 9 .

Embodiment 3

[0034] Embodiment 3: a kind of hand-held roof crack repairing machine, on the structural basis of embodiment 1, a blade is set on the edge of the groove of the grooved plate 3, and a frosted layer is set on both sides of the grooved plate 3, During the repair process, sand the crack edges.

[0035] The repair material mentioned above is made by mixing cement and gelatinous materials. For example, the cement mortar slit treatment disclosed in a hydraulic concrete surface slit sealing treatment method (authorized announcement number is CN 101994306 B) can be used. The material is used to repair roof cracks. After repairing, it has good adhesion and sealing properties, as well as waterproof and crack resistance.

Abstract

The invention discloses a hand guided roof crack repairing machine. The hand guided roof crack repairing machine comprises a stand composed of a chassis and an armrest frame which is obliquely arranged towards the back, a slotting plate and a pouring mechanism, traveling wheels are arranged below the chassis, the slotting plate is vertically arranged at the lower part of the front end of the chassis, the two lateral surfaces thereof are crossed in the working direction of the slotting plate to form a slotting edge for widening the crack opening, the pouring mechanism comprises a hopper, a pouring pump and a pouring pipe, a spring slot is formed in the pipe wall of the pouring pipe, one end of a spring arranged in the spring slot is fixed at the lower end of the spring slot while the other end is connected with the inner wall of a limit pipe which sleeves the pouring pipe, the pipe diameter of the limit pipe is larger than the width of the crack opening, and a ball is arranged at the bottom of the limit pipe. The limit pipe is clamped in two sides of the crack opening and jacked by means of the material gravity and the pouring impact force, the ball at the lower part of the limit pipe rolls along the crack edge to enable a nozzle of the pouring pipe to pour material in the crack along the crack direction, the material is saved, and the cost is lowered.

Description

technical field [0001] The invention belongs to the field of construction machinery, in particular to a hand-held roof crack repairing machine for repairing concrete cracks on the roof of bungalows or buildings. Background technique [0002] Nowadays, whether it is a residential building in the city or a one-story house or a multi-story building in the countryside, with the extension of the age of the house and natural erosion, there will be some unavoidable problems in the quality of the house, especially the roof is prone to cracks, Water seeps through cracks. [0003] In order to solve the problem of roof cracks, there are currently seam-filling glues on the market for repairing cracks. Although the seam-filling glue can repair cracks and prevent water seepage from roof cracks, the effect of the seam-filling glue will decrease as time goes on. It will gradually weaken, and the repaired cracks will still seep again, and, because the cracks are only blocked by the sealant,...
