[0023] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] See also Figure 1 and Figure 2 as well as Figure 3 and Figure 4 The figure shows a mechanism capable of solving the problem of uniformity of the transverse paving density of medium density slabs, comprising at least one set of lifting mechanisms 100 arranged along the width direction of the medium density slab paving belt 103 for adjusting the height of the medium density slab paving belt 103 in the width direction, each set of lifting mechanisms 100 comprises at least three sets of independently lifting and lowering lifting components 110, and these lifting components 110 are arranged at intervals along the width direction of the medium density slab paving belt 103 as required. The medium density slab paving belt 103 is used to transport medium density slabs 101.

[0025] The mechanism for solving the uniformity of the transverse density of the medium-density slab of the present invention requires at least 3 sets of independently liftable lifting assemblies 110. However, in theory, the more independently liftable lifting assemblies 110 there are, the better the effect of adjusting the transverse density (it is not recommended to exceed 24 sets at most), so N = 3, 4, 5... 24. Of course, less than 3 sets of independently liftable lifting assemblies 110 may be used as needed.

[0026] Each lifting assembly 110 includes a frame 104, a pad member 108 disposed on the frame 104 in a lifting manner, and a lifting drive mechanism installed on the frame 104 to drive the pad member 108 to move up and down.

[0027] As a special case of the present invention: the frame 104 may include a frame bottom plate 104a, two cushion blocks 104b, 104c and a frame top plate 104d, the two cushion blocks 104b, 104c are fixed on the frame bottom plate 104a by fasteners, and the frame top plate 104d is fixed on the two cushion blocks 104b, 104c by fasteners. A hole for a screw rod to pass through is provided on the frame bottom plate 104a. Two guide holes for guide rods to pass through are provided on the frame top plate 104d, and a guide sleeve is installed in each guide hole. Of course, the frame can also adopt other structural forms, and those skilled in the art can choose according to needs. No matter which frame structural form is adopted, it should fall into the protection scope of the claims of the present invention.

[0028] As a special case: the lifting drive mechanism of the present invention includes a threaded rod lifting mechanism and a threaded rod driving mechanism. Of course, the lifting drive mechanism can also adopt other lifting drive mechanisms, such as a crank-connecting rod mechanism, a four-bar mechanism, etc. The applicant of the present invention believes that no matter what form of lifting drive mechanism is adopted, it should fall within the protection scope of the claims of the present invention.

[0029] The power input end of the screw 106 in the screw lifting mechanism of the present invention is connected to the power output end of the screw driving mechanism, and the screw nut 106a in the screw lifting mechanism is connected to the pad component 108, so that during the rotation of the screw 106, the pad component 108 is driven to rise and fall through the screw nut 106a.

[0030] The lifting drive mechanism of the present invention is an electric lifting drive mechanism or a manual lifting drive mechanism. Figure 1 and Figure 2 The lifting drive mechanism shown in is a manual lifting drive mechanism, which at least includes a hand wheel 107 and a reducer 105, and the reducer 105 is mounted on the frame bottom plate 104a of the frame 104 by fasteners. The power input end of the screw rod 106 in the screw rod lifting mechanism passes through the hole on the frame bottom plate 104a and is connected to the power output end of the reducer 105, and the power input end of the reducer 105 is connected to the hand wheel 107. Of course, for those skilled in the art, the reducer 105 can also be eliminated as needed, and the hand wheel 105 can be directly connected to the power input end of the screw rod 106 in the screw rod lifting mechanism.

[0031] For the electric lifting drive mechanism, an electric motor can be used to replace the hand wheel 107.

[0032] The pad member 108 includes a flat pad 108a or an arc-shaped pad 108b, two guide rods 108c and a connecting plate 108d. The two guide rods 108c pass through two guide sleeves on the frame top plate 104d and are slidably matched with the two guide sleeves. The upper ends of the two guide rods 108c are connected to the flat pad 108a or the arc-shaped pad 108b, and the lower ends are connected to the connecting plate 108d; the connecting plate 108d is connected to the screw nut in the screw lifting mechanism.

[0033] The use of the arc-shaped plate pad 108 b can reduce the friction between the medium-density slab paving belt 103 and the medium-density slab paving belt 103 , thereby better protecting the medium-density slab paving belt 103 .
