Embodiment 1

[0030] Embodiment one, see figure 1 , a mobile formwork vehicle for expressway passageway culvert, characterized in that it includes a vehicle frame 1. The frame 1 includes a pole 11 . The lower end of each vertical rod 11 is provided with road wheels 3 . Horizontally adjacent uprights are connected together by a number of transverse connecting rods 12 distributed along the up-down direction. The transverse connecting rod 12 and the upright rod 11 are detachably connected together by bolts fitting the connecting plate. Adjusting bolts 13 are provided on both sides of the vehicle frame 1 in the width direction (the left and right directions in the figure, the width direction of the channel culvert during use). Adjusting bolts 13 protrude from the vehicle frame 1 along the width direction of the vehicle frame. The adjusting bolt 13 is arranged on the pole 11 . The adjusting bolts 13 are at least distributed into two rows along the up-down direction, and distributed into two...

Embodiment 2

[0033] Embodiment two, the difference with embodiment one is:

[0034] see Figure 4 , The vehicle frame 1 is provided with a static support foot 17 and a walking wheel installation rod 9 . Static support feet 17 and vehicle frame 1 are screwed together to realize liftable connection. Static support foot 17 can be adjusted to be lower than walking wheel 3. The road wheel mounting rod 9 includes a lower section 91 and an upper section 92 . The running wheel 3 is connected to the lower end of the lower section 91 . The upper end of the lower section 91 is slidably sleeved on the lower end of the upper section 92 . The lower section 91 is provided with a damping spring 93 supporting the upper section 92 . The upper end of the upper section 92 is provided with a connecting ring 921 . An inner ring 922 passes through the connecting ring 921 . The inner ring 922 is connected with the connecting ring 921 through the rubber ring 7 . The inner ring 922 is pierced with connectin...

Embodiment 3

[0041] Embodiment three, the difference with embodiment two is:

[0042] see Figure 9 , The road wheel mounting rod 9 is also provided with a drive mechanism 6. The inner ring 922 is rotatably connected to the rubber ring 7 , and the rubber ring 7 is fixedly connected with the connecting ring 921 .

[0043] The drive mechanism 6 includes a ratchet 61 , a pawl 62 for driving the ratchet, and a drive lever 63 . The ratchet 61 is coaxially connected with the inner ring 922 . The ratchet 61 is integrated with the inner ring 922 . The pawl 62 is fixedly connected to one end of the driving rod 63 . The upper section 92 is provided with a sliding hole 924 . The other end of the driving rod 63 can slide through the sliding hole 924 two-dimensionally. The lower end of the drive rod 63 is slidably hooked to the lower section 91 along the radial direction of the connecting ring 921 (see Figure 4 ) are fixed together. The driving rod 63 is provided with a storage hole 64 . Ther...

Abstract

The invention relates to machinery for construction, and in particular to a movable template vehicle for an expressway passageway duct. The movable template vehicle comprises a frame, wherein the frame is provided with traveling wheels, the upper end of the frame is provided with two main beams which are distributed along the longitudinal direction and extend in the transverse direction, two ends of each main beam extend out of the frame along the transverse direction, and each main beam is provided with two rows of hooks which are distributed along the transverse direction, two sides of the frame in the width direction are provided with adjusting bolts extending out of the frame and being used for adjusting the width of the passageway duct and the verticality of a template. By adopting the movable template vehicle for the expressway passageway duct, the problems that the time for building a steel-pipe support to install the template and pouring the concrete is relatively long, the mechanical and manual expense is relatively high and the safety potential hazard exists can be solved.

Description

technical field [0001] The invention relates to building construction machinery, in particular to a mobile formwork vehicle used for expressway channel culverts. Background technique [0002] In the process of expressway channel culvert construction, the traditional construction method is to install and bind segmental steel bars after the channel foundation construction is completed, use a crane to install the formwork, and erect steel pipe brackets in the channel for formwork support and reinforcement construction. Build and disassemble the construction in a cycle in turn until the construction of the entire channel culvert is completed. The construction time of this method is longer, the cost of machinery and labor is higher, and there are more potential safety hazards. Contents of the invention [0003] The invention provides a mobile formwork vehicle for expressway passageway culverts used in construction of passageway culverts, which solves the problems of long const...
