Description

Concrete repair truck

technical field

The utility model relates to a special vehicle for concrete construction, in particular to a concrete emergency repair operation vehicle, which is mainly suitable for emergency repair and emergency construction after damage to concrete engineering, especially for rapid emergency repair and emergency repair after damage to concrete engineering such as military airport pavement and wharf. establish.

Background technique

In the concrete construction process, concrete mixing production is the central link; at present, there are two modes of domestic concrete mixing production, namely, the commercial production mode of large concrete mixing plants and the on-site mixing production mode. Mixing plants are generally built around cities or large and medium-sized construction sites, while on-site mixing production is widely used in small construction sites far away from cities.

Concrete raw materials mainly include stones, sand, cement, etc. Each cubic concrete generally requires about 1000kg of stones, 800kg of sand, and 400kg of cement. For on-site concrete construction, the concrete batching machine (hereinafter referred to as the batching machine) is generally used to distribute and measure stones and sand to the concrete mixer (hereinafter referred to as the mixer). In the sand storage hopper, the two storage hoppers convey the material to the weighing hopper of the batching machine successively through the belt conveyor, and then the belt conveyor of the weighing hopper conveys the measured gravel and sand mixture in the weighing hopper to the lifting hopper of the mixer, and the lifting hopper will The gravel-sand mixture and the additional cement installed here are lifted into the main mixer together. In the case of auxiliary batching by a batching machine, the productivity of the mixer is generally 20-40m ³ /h.

Due to the large size of the batching machine, it is inconvenient to transport and install, so in some occasions where the amount of concrete construction is small, the mixer often does not use the batching machine to assist the batching, but manually adds stones, sand and cement to the mixer bucket. In this case, it is generally adopted to dig a pit at the place where the mixer is installed, and sink the mixing hoist into the pit so that the upper mouth is lower than the ground, so that the trolley can be used to assist in loading and unloading stones and sand; in this construction method, the productivity of the mixer is generally 5～10m ³ /h. General-purpose batching machines and mixers are both fixed-installation types. When transferring construction sites, they must be transported by heavy-duty vehicles. The loading, unloading and installation require the assistance of hoisting equipment; for emergency repairs of projects, especially the rapid repair and construction of military projects, the emergency repair time is urgent and universal. The above-mentioned characteristics of the equipment are difficult to meet the rapid response requirements of rushing to the scene and constructing immediately after arriving at the scene.

Engineering emergency repair, especially military engineering rapid repair and emergency construction, generally requires the equipment to be vehicle-mounted, so that it can be rushed to the site quickly, and basically saves the time for loading, unloading and fixing the equipment after arriving at the site. However, due to the large size of the general batching machine, it is difficult to realize vehicle installation. The general concrete batching machine is a two-layer mechanism, that is, the upper layer is equipped with a storage hopper, and the lower layer is equipped with a weighing hopper. The sand and gravel in the storage hopper are first unloaded into the weighing hopper for weighing, and then transported to the lifting hopper of the mixer. Such a structure leads to a large height of the batching machine, so the batching machine is installed on the ground for loading by the loader.

In order to meet the requirements of some engineering emergency repairs (especially some military engineering emergency repairs), solve the technical problem of integrating multiple related functions such as mixer, delivery pump, jet machine, etc. in one vehicle, the patent number is 200520072057.9 Chinese utility model patent and application The invention patent No. 200510040221.2 discloses a vehicle-mounted multifunctional concrete construction equipment. Its structure is: the pumping mechanism of the pumping jet machine, the spraying gun, the accelerator device and the compressed air device are installed on the chassis of the car; It is characterized in that: a mixer is installed on the chassis of the car, including its raw material lifting mechanism, stirring mechanism, hydraulic power device and electric control device.

This solution solves the problem of on-vehicle installation of small mixers suitable for manual feeding, but does not solve the problem of on-vehicle installation of batching machines. Therefore, the production capacity of the mixers in this solution is very small, especially to adapt to the characteristics of rapid repairs, it is not possible to dig holes on site In order to make the lifting bucket of the mixer sink to the upper mouth and be even with the ground, it is impossible to use a trolley to assist in loading, but to completely rely on manual lifting to load the bag. It can reach 4~5m ³ /h. Such productivity can only meet the construction needs of some small amount (less than 10m ³ ) concrete quick repair construction (quick repair generally requires 1-2 hours to complete concrete pouring), for many quick repair occasions with a concrete construction volume of 20-100m ³ , the corresponding vehicle-mounted Type concrete construction equipment must be equipped with batching machines and mixers at the same time to increase productivity.
