Embodiment 1

[0023] Such as figure 1 and figure 2 As shown, the vehicle-mounted composite material concrete mixing drum provided by the invention comprises: an outer cylinder wall (1) and an inner cylinder wrapped in the outer cylinder wall (1), and the outer cylinder wall (1) is made of reinforced fiber yarn After being impregnated with curable resin, it is formed by winding and curing on the outer surface of the inner cylinder through a winding process. The inner cylinder is formed by rotating the first helical member (2) through 180 degrees and passing the second helical member (3) through polyurethane The adhesive (4) is glued together, and the structure of the first spiral member (2) and the second spiral member (3) is the same.

[0024] In the vehicle-mounted composite material concrete mixing drum described above, the first helical member (2) and the second helical member (3) each include a helical blade (5) and a screw connected to the helical blade (5). The spiral inner cylinde...

Embodiment 2

[0028] A preparation method for a vehicle-mounted composite material concrete mixing drum, which specifically includes the following steps:

[0029] a, the preparation of the first helical member (2) and the second helical member (3): as figure 2 As shown, first the second spiral inner mold (9) is installed and fixed on the support; the spiral reinforced round rod (7) is installed and fixed on the end of the second spiral inner mold (9) with a polyurethane elastomer spacer In the groove (11); the first helical inner mold (8) and the helical outer mold (10) are installed on the second helical inner mold (9) successively, so that the first helical inner mold (8), A spiral sealed cavity is formed between the second spiral inner mold (9) and the spiral outer mold (10); inject polyurethane resin and its auxiliary agent into the cavity; after the resin is solidified, remove the spiral The outer mold (10), the first helical inner mold (8) and the second helical inner mold (9) form ...

Abstract

The invention discloses a vehicular composite concrete mixing drum and a method for manufacturing the same. The vehicular composite concrete mixing drum comprises an outer drum wall (1) and an inner drum wrapped in the outer drum wall (1). After being impregnated in curable resin, reinforced fiber yarns are wound on the outer surface of the inner drum via a winding process and then are cured on the outer surface of the inner drum to form the outer drum wall (1), and first spiral components (2) and second spiral components (3) are adhered with one anther by polyurethane adhesive (4) to form the inner drum. The vehicular composite concrete mixing drum is reasonable in structural design, high in abrasion resistance and corrosion resistance, long in service life and wide in application range, and is light. Besides, the method for manufacturing the mixing drum has the advantages that a special mold capable of realizing an integral injection molding function is designed according to structural characteristics of the inner drum of the concrete mixing drum, the outer drum wall is manufactured by a winding machine via the winding process, the manufacturing efficiency is high, and the mixing drum manufactured by the method is light and is high in abrasion resistance and corrosion resistance and low in manufacturing cost.

Description

technical field [0001] The invention relates to a building concrete mixing machine, in particular to a vehicle-mounted composite material concrete mixing drum used on a concrete mixing transport vehicle and a preparation method thereof. Background technique [0002] The rapid development of the construction industry has led to the promotion and popularization of commercial concrete. As an important equipment to realize the commercialization of concrete production, the demand for concrete mixer trucks has further increased and is widely used in highways, urban and rural construction, railways, airports and cement products. modern construction. As the core component of the concrete mixer truck, the mixing drum is not only a loading tool for the mixer truck to transport concrete, but also a working device for mixing concrete. Usually, the truck-mounted concrete mixing drum is a heavy-duty steel structure, and the loading volume is generally 8-12m 3 , affected by the manufactu...
